Remediation of lead acid battery wastewater and sludge synthesis of functionalized sorbents and manufacturing of fired clay bricks

Abstract

The lead acid battery LAB industry is one of the most polluting industries that generate highly contaminated heavy metal laden wastewater LABW as well as sludge LABS Two functionalized sorbents viz functionalized fibrous adsorbent FFA and functionalized mercerized husk FMH a bio resin were synthesized using a locally abundant waste biomass arecanut husk for the decontamination of LABW Both FFA and FMH achieved 99 removal efficiency of Pb II from an initial concentration of 32 m
