摘要
使用14-3-14·2Br型Gemini表面活性剂表面活性剂对钠性膨润土进行改性。采用电子扫描仪、红外光谱仪等设备对改性后膨润土的结构进行表征。利用14-3-14·2Br型表面活性剂对膨润土进行改性,并以改性后的膨润土作为吸附剂,探究该吸附剂对水溶液中有机蓝的吸附性能。判定最佳的吸附条件(如:时间、温度、吸附剂用量及水溶液的p H值)。通过实验可探究出改性膨润土对水溶液中有机蓝的吸附最佳条件是:吸附时间为40min,吸附剂用量为2.0g,最佳温度在50℃左右,p H值在5左右。
The use of 14 - 3 - 14·2Br type of Gemini surfactant of sodium bentonite was modified. Using electronic scanner, infrared spectrometer and other equipment of the modified bentonite was characterized. The bentonite was modified with 14 - 3 - 14·2Br surface active agents, and to the modified bentonite as adsorbent, the adsorption properties of adsorbent on organic blue in aqueous solution. To determine the best adsorption condition （such as： time, temperature, amount of adsorbent and aqueous solution of pH）. Through the experiment of modified bentonite on the optimum conditions for adsorption of organic blue in aqueous solution is： the adsorption time is 40min, adsorbent dosage was 2.0g, the optimum temperature is 50 ℃, and the solntion of the pH at around 5.
