Abstract

Heavy metal pollution has become a major problem surrounding our environment. Conventional heavy metal processing techniques were unsuccessful and expensive. As a result, in our current work, biochar and magnetic biochar have been used as an efficient, low-cost, safe, and environmentally friendly method for heavy metal removal for Pb+2. Rice husks were used to absorb Pb+2, and it was discovered that removability is affected significantly by the initial concentration of minerals, the adsorbent dosage, and the amount of adsorbent. Due to a direct increase in the amount of active adsorption sites available on the adsorbent surface, the produced biochar had a positive effect on improving the removal efficiency of heavy metals Pb+2, resulting in a higher removal efficiency of the heavy metal ions present, with 92.94% , at doses of 1 gm., adding the magnetization property to biochar prepared by doping with 𝐹𝑒3𝑂4 significantly improved the adsorption performance, with Pb+2removal efficiency reaching 97.96%. The addition of the magnetization property increased the number of active sites, expanded the adsorption surface field, and provided an attractive material for mineral ions, explaining magnetic biochars high adsorption performance.
