摘要

以活性炭粉末(PAC)、聚氨酯发泡剂为主要原料制备了一种新型高效腐植酸吸附剂——活性炭泡沫体

考察了腐植酸溶液pH值、腐植酸溶液初始浓度、活性炭泡沫体的使用量和吸附时间对吸附过程与吸附效果的影响。试验发现

活性炭泡沫体对腐植酸吸附平衡时间约为5 h;在酸性(pH值为3.5)及偏酸性(pH值为5.5)条件下

10%活性碳泡沫体对腐植酸吸附率较高

在腐植酸初始浓度低于10 mg/L时其吸附率达94%

初始浓度在(20~40)mg/L时吸附率亦达到60%~85%。试验结果表明:活性炭泡沫体是一种新型高效的吸附剂

在酸性与偏酸性条件下对天然水中腐植酸有很好的吸附效果;活性炭泡沫体吸附腐植酸符合langmuir模型。

Abstract

Taking powder of activated carbon(PAC)and polyurethane foaming agent as the main raw materials

a new type highly efficient sorbent for humic acid(HA)has been prepared

and influence of the pH value in HA solution

the initial concentration of HA solution

the dosage and absorbing time of the PAC foamer upon the adsorbing process and effectiveness being investigated.It has been discovered from the test that:the adsorption equilibrium time of PAC foamer for HA is 5 h;the 10% PAC foamer has comparatively high adsorbing efficiency under acidic conditions(pH value is 3.5 to 5.3);in the event of the initial concentration of HA is less than to mg/L

its adsorbing efficiency is up to 94%

while the initial concentration of HA is in a range of 20~40 mg/L

the adsorbing efficiency is 60%~85%.The results of test show that the PAC foamer is a new and highly efficient sorbent

boasting very good adsorbing effectiveness for HA in natural water under acidic conditions;the absorption of PAC foamer for HA tallies well with the langmuir model.
