摘要:
以累托石为吸附材料，聚乙烯醇（PVA）为粘结剂，海藻酸钠(SA)为稳定剂，含2%氯化钙的饱和硼酸溶液为交联剂，制备累托石复合颗粒.研究了累托石、聚乙烯醇（PVA）、海藻酸钠（SA）用量、交联浸泡时间、粒径等因素对累托石复合颗粒吸附性能的影响.结果表明：在静态吸附试验条件下，累托石：PVA=32、SA=003 g（累托石3 g）、交联时间4 h、粒径3 mm，制备得到的累托石复合颗粒对亚甲基蓝的吸附性能最好.该吸附过程符合准二级吸附动力学模型.
Abstract:
Composite particles of rectorite were made with rectorite as adsorbing material, polyvinyl alcohol (PVA) as caking agent, sodium alginate(SA) as stabilizing agent and saturation boracic acid containing percent 2 of calcium chloride as crosslinking agent. This paper was mainly based on effect of dosage of rectorite, PVA and SA, time of crosslinking soak and grain size on adsorption performance of composite particles of rectorite. The results showed that the best adsorption effect was gained at static condition when the dosage ratio of rectorite and PVA was 3 to 2, the dosage of SA was 0.03 g(rectorite 3 g), the crosslinking time was 4 h, and the grain size was 3 mm. The adsorption process accords with the pseudosecondorder kinetic model.
