Phosphate zeolite
WebSulphate-coated zeolite (SCZ) was characterized and employed for the removal of phosphate from aqueous solutions using both batch and column tests. Batch experiments were conducted to assess the sulphate dilution ratio, reaction time for coating, surface washing and calcination temperature during the synthesis of SCZ. WebThese functional features make zeolite a potential adsorbent for removing ammonia nitrogen and phosphate from rejected water. However, the cation exchange capacity of natural zeolite is fairly low. Additionally, the aluminum oxygen tetrahedron in the framework structure is negatively charged, which leads to weak phosphate adsorption capacity ...

WebApr 24, 2024 · Phosphate fertilizers are produced from rock phosphate (RP), a natural non-renewable resource. About 80% of the RP mined annually is used for fertilizer production and, considering the current level of consumption, it is expected that reserves will vanish in three centuries time [ 2, 4 ]. WebMar 30, 1999 · Considerable attention has been paid to zeoponic mixtures of NH 4 - or K-exchanged natural zeolites and sparingly soluble phosphate minerals (e.g., apatite; refs. 80 and 81). The small amount of Ca in the soil solution in equilibrium with the apatite exchanges onto the zeolite, thereby disturbing the equilibrium and forcing more Ca into …
