Natural dyes come from several sources and one of the more popular options is from plants. Plants have become the most used source because the material is easier to find and cheaper as compared to other sources like animals and minerals. Dyestuff from plant may reside in roots, berries, barks, leaves, wood, and flowers of it or lichen and moss on it. They provide colour and may produce colour that is not expected like a red flower that usually yields a yellow shade (Dagmar, 2012). However, certain material still yield the colour that is expected like red onion produces reds shade, blueberries produce blue to purple shades and walnut that yield brown shade.
Dyestuff can be obtained by extracting the natural resource and there is certain method …show more content…

al., 2011). In this study, Red spinach leaves are selected as the material for the natural dye. Its leave is round, thick, and rich green in colour like normal spinach but has a bright red colour on centre of leave and stem. Red spinach itself has many benefits to body and skin health because it contains essential amino acid, iron, magnesium, phosphorus, Vitamin E, potassium and Vitamin C. A reddish purple shade is the desired colour outcome of this study which contains anthocynanins (ACNs) which are water-soluble plants pigments responsible for the blue, purple, and red colour of many plant tissues (Beecher et. al., …show more content…

The testing involved are colour fastness test which includes washfastness, light fastness, and rubbing or crocking test, together with colour reflectance test. These three colour fastness testing is to study the colouring properties of dye on fabric and how mordant works to fix the red spinach dye on fabric. Washfastness test aims to evaluate the change of colour or staining from the fabric after washing it for certain time. Lightfastness is to assess the colour fading on the fabric after being exposed to light within a certain period. Rubbing is to evaluate the colour transfer to other fabric if frictions are applied to the fabric. The other testing is colour reflectance test and according to ASTM E1331-09 Standard Test Method for Reflectance Factor and Color it is to obtain the colour coordinates of dyed fabric by using spectrophotometers or colorimeters with either hemispherical or bidirectional

For this lab, zeolite and magnetized zeolite were synthesized and compared with charcoal to find out with would be the most effective in the sequestering of Procion Red dye. Finding the concentration and absorbance of each zeolite, magnetized zeolite, and charcoal, along with a calibration curve, the best adsorbent is determined. Charcoal was the overall best sequestration of the Procion Red dye, since the adsorbent was highest compared to the others. Introduction Pollution has increased in the environment over the years, so the purpose of this experiment is to find the best adsorbent of chemicals to reduce the pollution.

Record the amount of absorbance by converting transmittance every 5 minutes for a total of 20 minutes. Repeat all of these steps for the cantaloupe, banana, replacing the blank each time to recalibrate the spectrophotometer. After recording all the percent transmittance value, the data was then converted into absorbance value by using the absorbance conversion table. The information was placed on a plotted graph

To test the tear film integrity, fluorescein dye is applied to the temporal bulbar conjunctiva and the patient is instructed to blink several times to distribute the dye across the surface of the eye. Once the dye is spread, it is observed under a cobalt blue light allowing the dye to be clearly seen. A timer is run as the dye is observed and the examiner notes when the full thickness of the tear layer is seen to have evaporated . A normal, healthy result of a TBUT test will generally be ten seconds or more.

Spinach is thought to be of Persian origin. It has nutritional qualities and it is a leafy green with amazing proprieties to increase energy level, to improve vitality and the quality of the blood. There are several reasons for spinach to produce these effects, primarily due to the fact that it has large quantities of iron. Iron is an important mineral to the function of red blood cells which aid in transporting oxygen to different parts of the body, in energy production and DNA synthesis. Spinach is a good source of lots of vitamins such as vitamin K, vitamin A, vitamin C and vitamin B2 (Lewin, J, n.d).

The 3 concentrations of enzymes were 0.5 ml, 1.0 ml, and 2.0 ml of turnip extract, while the substrate consisted of 0.1ml, 0.2 ml, and 0.4 ml of hydrogen peroxide. In a separate tube, the control was made up of turnip extract and guaiacol, known as the color reagent. This was recorded the absorbance every 20 seconds for 3 minutes.

A brief on Egyptian blue Egyptian blue (cuprorivaite, CaCuSi4O10) was the first synthetic pigment ever produced by man; it is considered a great technology development in ancient Egypt from the 4th Dynasty (c.2613–2494 BC) till the Roman times, this pigment appeared in Egypt during the 3rd millennium BC [6]. This pigment consists of calcium copper tetrasilicate (cuprorivaite, CaCuSi4O10), a blue tabular crystal about 15 μm to 30 μm in length, residual silica (quartz and/or tridymite) and an amorphous silica-rich phase. This synthetic pigment was making by mixing calcium salt (carbonate, sulphate or hydroxide), a copper compound (oxide or malachite), sand (silica) and an alkali flux (sources of alkali could either have been natron from areas

Color Vision (Color Blindness Test) It’s startling to think that almost 5% of people suffer from color blindness. Color vision testing aims to determine your color recognition abilities (or lack thereof). This typically involves looking at colored numbers formed out of dots, where the numbers are set against a background with a contrasting color. Individuals suffering from color vision issues may see an incorrect number.

The ammonia: 1-butanol (1:1) solvent was the appropriate solvent to use for the column chromatography of food dye because it exhibited the properties of a good solvent system. A total 8 colored eluents were collected. The eluents had colors of pink, dark red, dark blue, dark green, light green, yellow, orange and light yellow respectively and

A dye is a coloured substance that has an affinity, a bond with a physical surface, to the substrate to which it is being applied. Dyes are usually soluble in water. Dyes are used to change the perceived colour of an object. Dyes consist of 2 main parts: chromohore and auxochrome. Before 1856, all dyes were obtained from natural resources.
