Overview of the Impact of Different Concentration of Acid Solutions in the Production of Adsorbents from Shrimp Waste and the Capacity to Eliminate Textile Colours

Textile dyes are a combination of organic compounds, chromophores, and auxochromes as activators of chromophore work and binders between colors and fibers. In the industry, a large amount of waste of textile dye is produced daily. Before discharge into the environment, the waste must be processed so does it contain less amount of dyes. Removal of textile dye can be carried out using an adsorption process, one of which uses adsorbents derived from chitin and chitosan. This study aims to provide an overview of the impact of different concentrations of acid solutions used in the manufacture of adsorbents from shrimp waste and their capacity as textile dye adsorbents. The method used in this study is the article review method by comparing the results of the published articles. The gathered result showed that several dyes could be eliminated using chitin and chitosan, such as rhodamine B, methylene orange, methylene blue, direct black 38, procion red, methylene violet, reactive red, direct blue 78, indigo carmine dye.
