Quantitative evaluation of biochars performances obtained from algae biomass in metal ions biosorption processes

Abstract

Nowadays, heavy metal pollution has become an acute problem. Due to toxic toxicity, persistence, and accumulation tendency, high concentrations of heavy metals are found in the environment, becoming an important factor in the degradation of the ecosystem. More and more cases of accidental pollution of inland or international waters, air, or soil with substances or products containing heavy metals are frequently reported in the media and are also the subject of concern in the scientific world. Algae biomass is widely found and has a wide range of uses, representing a valuable biomass resource due to its properties in solving various environmental problems, such as decontamination of soil and wastewater, etc
