【摘要】利用NZP族磷酸盐材料结构上的特点,将其作为一种新型吸附材料应用于吸附溶液中的Pb2+,研究了静态吸附容量、吸附动力学及吸附容量与静置时间的关系。结果证明NZP族磷酸盐材料对Pb2+离子确有明显的吸附作用,且吸附动力学符合Langmuir等温线。更多还原

【Abstract】 As a new absorption material,the structural characteristic of the NZP family phosphate materials was introduced in the article.One of the NZP family phosphate materials was used to absorb the heavy metal ion of Pb²⁺ in the water.The stationary absorption capacity,absorption dynamic and the relation between absorption capacity and the static time after churning up were studied.The results showed that the NZP family phosphate materials could absorb the ion of Pb²⁺ obviously,and the absorption dynamic was fit to the langmuir equation.更多还原
