Biochars evaluation for chromium pollution .

02.07.2020 · Subsequently, adsorptions of Cr from chromite mines wastewater by biochars were assessed. Also, the influence of biochars' dose (1 and 5 % w/w) on water and plant available Cr in overburden was determined for 90 days timespan. Maximum Cr (VI) adsorption was relatively higher from synthetic Cr solution by MCBC (142.8 mg/g).
