Insight into modified biochars and their immobilizing effects on heavy metal(loid)s in contaminated soils: Mechanisms and influencing factors

Soil contamination by heavy metal(loid)s is a considerable environmental concern, and immobilization is a promising way to reduce toxicity. In recent years, modified/engineered biochars have gained enormous attention for their use in soil remediation, and various studies have reported notable results from their application and their ability to immobilize heavy metal(loid)s. In this review, a summary of publications on the utilization of modified biochars is presented to address the heavy metal(l...
