Nitrogen and phosphorus play essential roles in ecosystems organisms. However, with the development of industry agriculture recent years, excessive N P have flowed into water bodies, leading to eutrophication, algal proliferation, red tides, which are harmful aquatic Biochar has a high specific surface area, abundant functional groups, porous structure, can effectively adsorb nitrogen water, thus reducing environmental pollution, achieving reusability elements. This article provides an overview preparation biochar, modification methods advancements adsorption by factors influencing as well mechanisms. Furthermore, difficulties encountered future research directions regarding biochar were proposed, providing references for application adsorption.

In this study, we aimed to develop an absorbent for efficient removal of heavy metals. We developed a composite (BC-IOx) using biochar (BC) obtained by carbonizing rice hull, type biomass, and iron(III) nitrate nonhydrate (IO). The bonding strength between BC IO was increased through ultrasonication with high energy at 25 ℃ 2-h heat treatment process 350 ℃. Brunauer-Emmett-Teller analysis showed that BC-IOx had specific surface area, which proportional iron loading provided abundance active metal adsorption sites. This effectively removed Pb(II) As(V). addition BC-IO3 Pb(II)-contaminated water 120 min absorption capacity 90.21 mg/g from 18.12 unmodified BC. As(V) 8.33 65.34 BC-IO10. addition, the potential mechanism discussed detailed chemical physical analyses. synthesis oxide can inspire cost-effective straightforward production absorbents be utilized on large scale.
