One-step process for purification and organic modification of attapulgite

The invention discloses a one-step process for purification and organic modification of attapulgite. The one-step process for purification and organic modification of attapulgite provided by the invention comprises the following steps: step 1, carrying out preliminary purification on attapulgite raw ore to obtain a preliminarily purified attapulgite suspension; and 2, carrying out organic modification and further purification on the primarily purified attapulgite suspension. According to the method, purification and organic modification of the attapulgite can be completed in one step, the process is simple, the water consumption is low, the cost is low, less waste water is generated, the environmental pollution is small, and the method conforms to green industrial production advocated by the country. 本发明公开了一种凹凸棒石提纯和有机改性的一步法工艺。本发明所提供的凹凸棒石提纯和有机改性的一步法工艺包括：步骤1、对凹凸棒石原矿进行初步提纯，得到初步提纯的凹凸棒石悬浮液；步骤2、对初步提纯的凹凸棒石悬浮液进行有机改性和进一步提纯。本发明能够一步完成凹凸棒石的提纯和有机改性，工艺简单、耗水量少、成本低，产生的废水少，环境污染小，符合国家倡导的绿色工业化生产。
