Empirical modeling and optimization by active central composite rotatable design: brilliant red he-3b dye biosorption onto residual yeast biomass-based biosorbents

HIGHLIGHTS

SUMMARY

Brilliant Red HE-3B is a reactive dye and its biosorption from wastewater resulting from the process of dyeing textiles, by using a residual Saccharomyces pastorianus yeast (available at large scale, easy and safe to use) immobilized in sodium alginate (using two different practice techniques) as biosorbent has been analyzed and reported, as corresponding to a maximum biosorption capacity of around 224.47-555.55 mg/g. The validated biosorption process of the studied reactive dye onto immobilized residual biomass is mathematically modelled considering some specific variation domains of three important independent variables with . . .
