| 摘 要： | 本论文以正硅酸乙酯为硅源、偏铝酸钠为铝源、四丙基氢氧化铵为模板剂,利用水热合成法制备ZSM-5沸石分子筛并将其应用到吸附水中六价铬的研究,考察了吸附时间、铬酸钾溶液pH值、吸附剂用量、吸附温度对吸附效果的影响。结果表明,最佳吸附条件是:吸附剂的使用量为0.5g,铬酸钾溶液pH值为5,吸附时间为60 min,吸附温度为30℃,此时,六价铬的去除率最高,达到了93.46%。

| Abstract: | ZSM-5 zeolites have been synthesized with hydrothermal synthesis method using tetraethyl orthosilicate as silica source, sodium aluminate as aluminum source, four propyl ammonium hydroxide as templating agent. The adsorption process conditions were studied including adsorption temperature, adsorption time, pH value of potassium bichromate solution and adsorbent dosage. The optimum conditions are as follows： adsorption temperature was 30 ℃, adsorption time was 60 min, pH value of potassium biehromate solution was 5, adsorbent dosage was 0.5 g. The removal rate of Cr6＋ was 93.46% under the above conditions. |
