ZIF-8 as a reactive adsorbent for phosphate removal from treated waste water

Abstract

Phosphate is one of the most important elements of plant, which can enhance photosynthesis and carbohydrate transport. Phosphate can promote the synthesis of protein, and it is conducive to the reduction and utilization of nitrate by nitrogen fixation. Phosphate participates in the synthesis of plant fat, which can improve crop adaptability to the external environment. However, if phosphorus pollution is discharged directly, it will lead to serious environmental pollution, such as nutrient enrichment of seawater. ZIF-8, a subclass of MOF, has emerged as a new kind of porous crystalline materials with excellent properties such as uniform micro-pores, accessible pore volumes, large surface areas as well as exceptional chemical and thermal stabilities, making it potentially interesting candidate for adsorbing phosphate from waste water.
