摘要 目前广大学者选择将羟基氧化铁负载在某种吸附剂上,究其原因在于在水溶液中,负载在吸附剂上的羟基氧化铁的分散性能大大提高,处理效率也相应提高。利用负载有羟基氧化物的复合物来吸附锰,升高局部浓度,并投加Na Cl O、KMnSO4来氧化锰,然后去除饮用水中的锰。实验结果显示,当投加适量氧化剂时,锰的去除率达98%以上,即该复合物能有效提高载体的吸附性能。 At present,the majority of scholars choose to load iron oxyhydroxide on some kind of adsorbent.The reason is that in the aqueous solution,the dispersion performance of iron oxyhydroxide loaded on the adsorbent is greatly improved,and the treatment efficiency is also correspondingly improved.In this paper,a compound loaded with oxyhydroxide was used to adsorb manganese,increase the local concentration,and add NaClO,KMnSO4 to manganese oxide,and then remove manganese from drinking water.The experimental results show that when the proper amount of oxidant is added,the removal rate of manganese is over 98%,which means the complex can effectively improve the adsorption performance of the carrier.
