Research Progress on the Adsorption and Migration Mechanism of Heavy Metals by Algae
In recent years,the pollution of heavy metals and nutrient salts(nitrogen,phosphorus,etc.)has become increasingly serious,which threaten human health and damage the sustainable development of economy,society and Environment.Nitrogen and phosphorus nutrients can easily cause algal blooms,and algal cells have a certain adsorption capacity for heavy metals in the water environment,which can effectively adsorb and treat heavy metal pollution and have huge market potential.This article aims to repair heavy metal pollution in the water environment,reviews the influencing factors of microalgae cells adsorbing heavy metals,analyzes and compares the adsorption capacity of different algae to heavy metals,as well as the adsorption effects of living and dead algae cells on heavy metals.It summarizes the adsorption,enrichment,and migration mechanisms of microalgae cells towards heavy metals,and points out the research focus and direction of microalgae cells accumulating heavy metals in the next stage.
