Biosorption of Azo-dye using Marine macro-alga of Euchema Spinosum

A study on various biosorbents in promoting environmental and economic sustainability has become a current attempt by researchers for removal of synthetic dye from industries. Marine algae are listed as excellent candidates for alternative biosorbents. Therefore, in this study, five indigenous speci...
