Abstract
In the present study, we have prepared a biochar using the waste material of groundnut.
Malachite Green is a synthetic refractory organic molecule that is created from
triphenylmethane and has stable chemical features. MG and its metabolite, leucomalachite
green, are carcinogenic and genotoxic, posing a risk to the immune and reproductive
systems. According to researchers, MG has a negative influence on critical components
of soil ecosystems, causing severe harm to the environment.
As a solution to the aforementioned problem, we have used this biochar to degrade
MG from polluted water. We have also treated the biochar with HCl, zinc chloride,
phosphoric and sodium hydroxide, tested the extent of removal at different pH, temperature,
contact time and adsorption doses and results are discussed here.
