Removal Of Phosphate,Fluoride,Arsenic From Wastewater By Using Functionalized Rubber Latex Templated Silica

Water pollution has always been a problem of our country. In recent years, eutrophication has become a serious threaten to various water sources of our country. Most of the water has different degrees of phosphorus contamination. At the same time, our country has the hardest hit of fluoride pollution and dental fluorosis. Meanwhile other diseases that caused by excessive fluoride have a serious influence on the health of the people. Arsenic pollution has become a main contamination factors in our country. In the context of this, it is definitely critical to develop efficient, green adsorbents for sewage treatment.In this paper, rubber latex were used as bio-template to synthesize amino functionalization slica material. Experiments show that the series of materials are good at phosphorus removal. The maximum adsorption capacity of this materials is39.35mg/g. In addition, the amount of material, reaction time, the effect of pH, the initial concentration of phosphorus and other factors are investigated to study the phosphorus performance of this material. It turned out that when initial phosphate concentration was5mg/L, the amount of this material was0.02mg/L, adsorption temperature was25℃, solution pH value was7, adsorption time was1.5h.Through the study on the properties of fluoride removal, the fluoride in the water body can reach a certain removal effect. Experiments show that when initial fluoride concentration was9mg/L, the amount of this material was0.05g/L, adsorption temperature was25℃, solution pH value was7, adsorption time was3.0h, the equilibrium adsorption capacity of phosphate was19.37mg/g. We also study on the properties of arsenic removal, when initial arsenic concentration was5mg/L, the amount of this material was0.2g/L, adsorption temperature was25℃, solution pH value was7, adsorption time was6.0h, the equilibrium adsorption capacity of phosphate was10.47mg/g.Though the study on the removal of phosphate, fluorine, arsenic from wastewater by using functionalized rubber latex templated silica. We come to the conclusion that the performance on fluoride removal is better than that of arsenic and phosphorus removal.
