一种酸改性膨润土吸附剂及其制备方法
摘要：
本发明提供了一种酸改性膨润土吸附剂及其制备方法，所述膨润土吸附剂总孔体积为0.20-0.40cm3/g，比表面积为90.0-160.0m2/g，其制备方法包括：将原料膨润土粉末与酸的水溶液混合；将混合好的浆液进行水热反应处理；将水热反应处理后的膨润土浆液进行抽滤；将抽滤后的改性膨润土滤饼进行烘干、粉碎，得到所述的膨润土吸附剂。本发明的改性膨润土具有较高的比表面积，在吸附方面具有更好的性能。
摘要（英）：

The invention provides an acid modified bentonite adsorbent and a preparation method thereof. According to the acid modified bentonite adsorbent provided by the invention, the total pore volume is 0.20-0.40cm<3>/g, and the specific surface area is 90.0-160.0m<2>/g. The preparation method of the acid modified bentonite adsorbent comprises the following steps of mixing a bentonite powder as a raw material and an aqueous solution of acid; carrying out hydrothermal reaction treatment on the mixed slurry, and performing suction filtering on the bentonite slurry after the hydrothermal reaction treatment; and drying and crushing a modified bentonite filter cake after suction filtration to obtain the bentonite adsorbent. With the adoption of the acid modified bentonite adsorbent, the modified bentonite has higher specific surface area and has good performance in the aspect of adsorption.
