摘要：

In order to improve the adsorption performance of Attapulgite (ATP) on dyes. The ATP activated with hydrochloric acid was organic modified with silane coupling agent KR570. And the modified attapulgites was characterized by Fourier transform infrared spectroscopy and X-ray diffraction technique. By evaluating the activation index, the optimum modified condition as follow: KR570 dosage was 30 wt%, based on the quality of ATP, the modified time was 2 h and modified temperature was 80 degrees C. The results of adsorption experiments suggested that the modified attapulgite had a higher adsorption capacity for removing methylene blue. While adsorption of methylene blue on KR570-ATP, the decoloration rate increased to 79.55 %. Owing to its high absorption capacity and low cost, attapulgite modified with KR570 has potential value in the removal of methylene blue waste waters in engineering application.
