Impact of different concentrations of alginate in alginate-yeast hydrogel biosorbent

Abstract

Dyeing industry wastewater is one of the major environmental problems.Biosorption technology is regarded to be inexpensive and ecologically beneficial. Spent brewery yeastused in this researchis proposed as a promising adsorbent [1] but free cells are unsuitable due to separation problems which leads toimmobilization as an importantpartof the practical applicationof biomass biosorption. Alginate is well known;widely usedand inexpensivematerial and the extrusion technique is theeconomical and ecofriendlyencapsulation technique for immobilization with alginate as a carrier.
