Electro-assisted adsorption of heavy metals from aqueous solutions by biochar

open access: yes, 2020
Electro-assisted adsorption was investigated for Pb2+, Cu2+ and Ni2+ removal using date seed biochar (DSB-Electro). Compared with pristine biochar, the results showed that DSB-Electro effectively increased the adsorption capacity of Pb2+, Cu2+ and Ni2 ...

Heavy metal transport with adsorption for instantaneous and exponential attenuation of concentration

open access: yesScientific Reports
Heavy metal pollutant is a serious problem in environmental pollution, and it is very difficult to eradicate once it enters the soil. As heavy metal adsorption has been proven to occur, the heavy metal’s behaviour can be modeled as a transport equation ...
