Advantages And Disadvantages Of Textile Industry

The textile Industry considers the largest sectors that produce an amazing 60 billion kilograms of fabric per year, utilizing around 9 trillion gallons of water [2]. Treating dye effluent resulting from textile and many industries such as biocides, dyes, detergents, paints, inks, etc. have become one of the most problematic problems that face countries [3, 4]. As these dyes consist of different chemical compounds such as sulfuric acid, copper, chromium, and other metallic elements which cause water pollution. Countries started to establish factories and technologies for treating wastewater resulting from textile and industries that use dyes and forced all factories to reduce and recycle water in the process to minimize toxic chemicals [7].

in recent years, new technologies have been developed to treat dyes waste and reduce pollutants such as molecularly imprinted polymers (MIPs) [28-34].which consider cheap ,safe ,and have high ability to remove water pollutants more than other classical methods

Molecularly Imprinted Technique (MIT) was first appeared in the early 1930s. Then the technique was explained by Polyakov in 1931 [35], as the molecularly imprinted polymers are artificial polymers that produce specific cavities for target molecules. And prepared by copolymerization of the complex formed by interacting of the template and functional groups of monomer through covalent or noncovalent bonds with cross-linking, then removal of imprinted template leaves complementary cavities behind to the template molecule [36]. These polymers have a tendency for the functional group of the template molecule. Preparation of molecularly imprinted material is shown in fig. (3). MIPs have been used in many fields [37] such as catalysis [38], sensors [39], chemical separations [40], and solid phase extraction

The physicochemical features of the prepared MIP nanoparticles were investigated by developed techniques as XRD, FTIR, and HRTEM. However, the efficiency of the prepared MIP for trapping Congo red dye from wastewater was monitored by the UV-visible spectrophotometer. The influence of MIP dose, dye concentration, pH and temperature on MIP uptake was studied, three models (Langmuir, Freundlich [46-50], and Temkin [51, 52], have been used to describe the adsorption process of Congo red onto Chitosan MIP. Furthermore, kinetics of Congo red adsorption on Chitosan MIP will be indicated using a pseudo-first order [47], a pseudo-second order [53, 54] and interaparticle diffusion [47-55], and pictures for experimental work for removal Congo red dye using chitosan MIP are shown in
