The extensive discomfort in the expulsion of toxic pollutants even at mild concentrations has demanded the need for prompt methods for the evacuation of dyes and heavy metals. The effective method for depuration of dye from the effluent is by sorption. Chitosan is a bio-polymer which is gaining an increasing interest as one of the sorbents. It was obtained from the crab shells by undergoing several chemical processes and used as an adsorbent for dye, metal removal and also for pharmaceutical purposes. Cross linking it with other co polymers will increase the capacity of adsorption to a maximum level. Fish scales are considered to be a major waste in the food industry and since it takes a long time for decomposing it is considered to be one of the pollutants. Hence it is utilised by converting it into activated carbon by preliminary treatment and into a muffle furnace. The obtained activated carbon is combined with chitosan by using a cross linker and utilised for adsorption mechanism. To analyse the effect of chitosan cross linked with activated carbon obtained from fish scales in adsorption of dye Reactive Blue 9 (RB9) to evaluate the adsorption studies, kinetics, mass transfer studies, thermodynamics of the bio adsorbent.
即使在低浓度下，有毒污染物的广泛不适也要求需要迅速的方法来排出染料和重金属。从废水中去除染料的有效方法是吸附。壳聚糖是一种生物聚合物，作为吸附剂之一，越来越受到关注。它是通过经历几个化学过程从蟹壳中获得的，并被用作染料、金属去除和药物用途的吸附剂。与其他共聚物交联将使吸附能力提高到最高水平。鱼鳞被认为是食品工业的主要废物，由于它需要很长时间才能分解，因此被认为是污染物之一。因此，通过初步处理将其转化为活性炭，并在马弗炉中进行处理，就可以将其转化为活性炭。所得的活性炭与壳聚糖一起使用交联剂，用于吸附机制。为了分析从鱼鳞中获得的壳聚糖与活性炭交联在吸附染料活性蓝 9（RB9）中的作用，以评估吸附研究、动力学、质量传递研究、生物吸附剂的热力学。
