The use of synthetic chemical dyes in various industries, including plastics, paper manufacturing, cloth dyeing, printing and leather treatment, has increased considerably over the last years, resulting in the release of dye-containing effluents into the aquatic and soil ecosystems. There are many techniques to remove the waste after dying process (coagulation, chemical precipitation, reverse osmosis, extraction, filtration, biological treatment and adsorption). The releasing of dyes from many industrial plants is environmentally hazardous. The most important goal for the waste water purification is to find the low-cost adsorbents with high selectivity and long life. In our study, an effort has been made to prepare efficient composite materials for dyes removal from aqueous solution based on medium molecular weights deacetylated chitin i.e. poly(D-glucosamine) and a bio-degradable nontoxic anionic polysaccharide sodium alginate filled with magnetite nanoparticles. Alginate composite beads coated with poly(D-glucosamine) were prepared using layer-by-layer (LbL) deposition method. During the adsorption process the concentrations of dyes in solution waste were determined according to the general spectrophotometer method.
