摘要:
以酸和Fe2+为改性剂,微波处理下对膨润土进行改性,将改性后的膨润土用于处理含高活性磷(PO43-)水体。考察了微波辐射功率和时间、改性剂质量分数(H2SO4和FeSO4)、改性膨润土投加量、pH值和反应时间等对活性磷的去除效果影响。实验结果显示,在微波辐射为350 W、时间为5 min,30 g钠基膨润土用50 mL质量分数8%的H2SO4和质量分数4%的FeSO4溶液制备的改性膨润土效果最好。微波改性Fe2+掺杂酸改性膨润土的层间距和比表面积比未改性膨润土分别增加了52.2%和80.2%。改性膨润土投加量为0.10 g,处理100 mL初始质量浓度为10 mg·L-1的含活性磷(PO43-)废水,pH值在7左右,搅拌3 min,处理效果最好,且改性后的膨润土对DRP吸附等温曲线符合Freundlich吸附等温曲线。将该实验结果应用于处理闽南师范大学校园内3种富营养化的水体(三湘江、景观池塘和达理小河)中的活性磷,去除率可达到84.67%~97.30%。
Abstract:
Acid and Fe2+modified bentonite was prepared under microwave radiation,and its removal of dissolved reactive phosphorus([PO3-4],DRP)in water was also discussed. Effects of microwave power and time,mass fraction of modification reagent,bentonite dosage,pH and reaction time on DRP removal in wastewater were investigated. The results show that the performance of modified bentonite is best with 30 g bentonite dosage in 50 mL(mass fraction 8% of H2SO4 and 4% of FeSO4) at microwave power 350 W for 5 min. Compared to the unmodified bentonite,the basal spacing values and specific surface area of acid and Fe2+ modified bentonite increase by 52.2% and 80.2% respectively. The treatment effect of DRP is best with 0.10 g of modified bentonite in 100 mL of wastewater with 10 mg·L-1 DRP,at pH value of 7.0 and reaction time of 3 min. The curves of DRP adsorption on the modified bentonite were expressed with Freundlich isotherm equations. The material was used to deal with the three eutrophic waters(Sanxiang River,landscape pool and Small River in Dali,all of them were in the campus of Minnan Normal University),the removal rates of DRP were 84.67%-97.30%.
