Research status of adsorption of phosphate in water by metal modified biochars
Excessive phosphorus in water will seriously affect the growth of animals and plants.How to ef-fectively remove excessive phosphate in water is very important.Adsorption method is widely concerned because of its advantages of low cost and easy operation.Biochar is used as adsorbent because of its low cost and high stability.Metal modification is an effective method to improve the adsorption of phosphate in water by biochar.Based on the research results of phosphate adsorption by metal modified biochar at home and abroad in recent years,the influencing factors and adsorption mechanism of phosphate adsorption by metal modified biochar were summarized.Provide theoretical basis and scientific basis for future research.
