Preparation method of cadmium ion resistant modified natural sodium bentonite waterproof blanket
The invention provides an anti-cadmium ion type modified natural sodium bentonite waterproof blanket preparation method, which comprises: S1, natural sodium bentonite modification: S101, mixing refined natural sodium bentonite, a hydrochloric acid solution and sodium dodecyl sulfate according to a ratio of 1 kg: 20 L: 0.7 kg, stirring, and standing; s102, carrying out solid-liquid separation on the mixed solution after standing, and taking out a solid; s103, washing the taken-out solid by using an ethanol solution, and then drying; s104, grinding and sieving the dried solid, so as to obtain modified natural sodium bentonite powder; and S2, locking the modified natural sodium bentonite powder between the geotechnical cloth and the plastic woven cloth to prepare the cadmium ion resistant modified natural sodium bentonite waterproof blanket. The cadmium ion resistant natural sodium bentonite waterproof blanket prepared by the invention has good adsorption and isolation effects on cadmium ions, can effectively prevent diffusion of the cadmium ions, and prevents daily environmental pollution.
本发明提供了一种抗镉离子型改性天然钠基膨润土防水毯制备方法，包括以下步骤：S1.天然钠基膨润土改性，S101.取精化后的天然钠基膨润土与盐酸溶液、十二烷基磺酸钠按比例1kg∶20L∶0.7kg混合，然后搅拌、静置；S102.将静置后的混合液进行固液分离，取出固体；S103.使用乙醇溶液洗涤取出的固体，然后干燥；S104.将干燥后的固体进行研磨、过筛，得改性天然钠基膨润土粉末；S2.将改性天然钠基膨润土粉末锁定在土工布和塑料编织布之间，制成抗镉离子型改性天然钠基膨润土防水毯。本发明制得的抗镉离子型天然钠基膨润土防水毯，对镉离子有良好的吸附、隔离效果，能有效阻止镉离子扩散，防止日常环境污染。
