Removal of Zinc Ions from Aqueous Solutions with the Use of Lignin and Biomass Part II

Abstract In response to the trend toward sustainable management of by-products from pulp and paper industry as well plant waste, practical economical methods are being developed use them in a way that does not pose threat environment. The main aim research was study possibility using lignin biomass biosorbents for removal zinc ions aqueous solutions. secondary build an optimal multilayer system made selected during order obtain highest sorption efficiency determine best conditions process. effectiveness ion assessed appropriate combination sorbents such lignin, oat bran, rice husk, chitosan, pectin, sodium alginate, pine bark, coconut fiber activated carbon, on basis literature data preliminary results tests carried out FTIR AAS. component separated black liquor. Results indicate Zn based fiber, which maximum 95%. also showed increase process temperature, mass used alkaline pH factors sorption. It can be concluded ecological water They safe environment, produced renewable sources, or waste materials, is part development circular economy currently promoted EU.
