| Abstract: |
| A new kind of modified amorphous silica materials HTS-n（s） containing both acidic and basic centers was synthesized.Both large BET surface area and 3-4 nm micropores of the composites were obtained after they were soaked with alkaline solution.This new material can selectively adsorb and remove the industry dyes infectants such as malachite green（MG） and crystal violet（CV） in culture water.After the centrifugation to separate the solution and the solid,the amounts of residual dye in solution were analyzed by liquid chromatography-tandem mass spectrometry（LC-MS/MS）.These modified silicas exhibited a much better adsorption capacity for industry dyes such as MG and CV than that of active carbon and zeolite NaY. |
