环境污染物的增加导致使用天然沸石等低成本材料,证明其有效的水处理。天然沸石从雅Hannoun(本地)和进口沸石,clinoptilolite-rich从美国获得的凝灰岩叙利亚沸石的凝灰岩,和合成八面沸石- 13 x被用作吸附剂。描述原始和改性沸石的研究来验证他们的物理化学和矿物学性质,为了注意任何变化发生在沸石的改性。使用的可行性从水中surfactant-modified沸石去除苯胺及其衍生物浓度的宽带(5 - 200毫克l - 1)被批实验评估。结果表明,显著增加苯胺及其衍生物的吸附能力可以实现加载hexadecyltrimethylammonium,阳离子表面活性剂,在沸石表面单层覆盖。吸附平衡进行了在不同初始浓度和pH值变化不同于3 - 11所示。朗缪尔吸附等温线和弗伦德里希被应用于实验数据。弗伦德里希最佳拟合的数据模型。发现苯胺的去除效率利用clinoptilolite-rich凝灰岩最大吸附最高50%相比其他沸石。删除N-Methylaniline达到最大效率利用Syrianzeolite高达69.5%。 A decrease in N,N-Dimethylaniline removal by surfactant-modified zeolite, and the maximum efficiency removal was 16% by using Jordanian-Faujasite. The results show that the optimum pH of the adsorption of aniline and its derivatives by surfactant-modified zeolite was almost in acidic and neutral pH conditions. Characterization of raw and surfactant-modified zeolite was carried out using several techniques such as cation exchange capacity, X-ray diffraction, X-ray fluorescence, scanning electron microscopy, and Fourier Transform Infrared Spectroscopy. UV/VIS spectrophotometer was used in equilibrium analysis.
