Abstract

In recent years with increasing pollution and development there is a need of easily operatable, less costly and no secondary waste generation and environment friendly treatment methods required. It is an attempt to study as degradation and decolorization of reactive azo dyes by seaweed biomass of Kappaphycus alvarezii. This present paper discussed the color removal capabilities of dry seaweed biomass of Kappaphycus alvarezii (C) which gives 93.61%, 90.66% and 21.94% decolorization from P1, P4 and P6 (reactive azo dyes) respectively. The FTIR study shows that the major dye functional groups were completely removed indicates the transformation or breakdown of dye molecules by the active sites of the seaweed biomass creates excellent result for the biodegradation and biodecolorization. After treatment the accumulated seaweed biomass was utilized for biocompost preparation as by-product and its applicability was studied by germination of Vigna radiata and Triticum aestivum. Pigment analysis chlorophyll-a, chlorophyll-b, total chlorophyll and carotenoid was studied indicates the pigment concentration was found higher as compared to control (without compost) in both the plant species which represents the applicability of accumulated seaweed biocompost creates sustainable approach as by-product and no secondary waste generation can be used in waste water treatment systems.
