    Abstract: A new method to remove the colour from textile wastewater using porous crab shell and chitosan beads as adsorbents is described. The delivery of colour in the form of dyes onto textile fibers is not an efficient process. As a result, most of the wastewater produced by the textile industry is coloured. Colour pollution in aquatic environments is an escalating problem, despite the fact that there has been substantial research into the modification of the dyeing process to improve the level of affinity/fixation of the dye stuffs onto the substrate. The biotechnology approach to colour removal from textile effluent has been investigated. However, in this report, we present here concerns the use of crab shell and chitosan powder for the reduction of water-soluble dyes present in textile dyeing wastewater. Removal of colour from aqueous solution with crab shell and chitosan powder was studied by means of solid-phase microextraction (SPME) and determined by gas chromatography/mass spectrometry (GC/MS).
