| 摘 要： | 利用Al3+离子较易水解聚合的性质，微波辅助合成了keggin Al13原位柱撑改性膨润土(PMCs)，并探究了其对微污染饮用水中磷元素的去除作用，研究表明，PMCs对磷的混凝和去除作用优于原土、工业 PAC和传统的柱撑改性膨润土(CPMCs)；影响除磷效果的主要因素有：搅拌时间、搅拌速度、水样的pH值以及初始浓度等，其最佳除磷条件是：在500 mL 10 mg/L含磷水样中加入1.5 g改性膨润土，搅拌速度为180 r/min，搅拌时间为5 h，水样pH为6～8。 |
| 关 键 词： | 改性膨润土 微波合成 原位柱撑 微污染饮用水 除磷 |

| Abstract: | Making use of the character of Al3+ which is prone to hydrolysis and polymerization,the modified bentonite in-situ pillared of keggin Al13(termed as PMCs)were made by microwave radiation,and the capability of removing phosphorus with PMCs were researched.The results showed that the PMCs is better than others,such as,the raw soil,the industrial aluminium polychlorid,and the traditional pillared bentonite(CPMCs);the major factors affecting the result of removing phosphorus with PMCs are stirring time,stirring... |
| Keywords: | modified bentonite microwave synthesis in-situ pillared micro-polluted drinking water phosphor removal |
