天然斜发沸石除重金属离子铅再生剂的选择及应用条件的确定

Selection on Regenerated Catalyst for Natural Clinoptilolite after Absorbing Pb^(2+) from Wastewater and Determination of Use Condition

对潍坊涌泉天然斜发沸石吸附废水中重金属离子铅及其再生剂的选择和应用条件进行了研究,结果表明NaCl为最佳再生剂。静态再生试验得出再生剂的最佳应用条件。动态试验表明,再生沸石具有较强的铅离子吸附能力,可以多次再生循环利用。

In this paper, the selection and determination of use condition on regenerated catalyst for the natural clinoptilolite from weifangyongquan of shandong province after absorbing Pb^2＋ from wastewater were study. The research indicated the best regenerated catalyst is NaCl. Under static test, the optimal codition of regenerated catalyst was determined. The dynamic test indicated that the absorbtion capacity of regenerated zeolite is strong and so the natural clinoptilolite can be circulatively used many times.
