This study aimed to investigate the efficiency of 3A zeolite as a novel adsorbent for removal of Rhodamine B and Malachite green dyes from water samples. To increase the removal efficiency, effecting parameters on adsorption process were investigated and optimized by adopting Taguchi design of experiments approach. The percentage contribution of each parameter on the removal of Rhodamine B and Malachite green dyes determined using ANOVA and showed that the most effective parameters in removal of RhB and MG by 3A zeolite are initial concentration of dye and pH, respectively. Under optimized condition, the amount predicted by Taguchi design method and the value obtained experimentally, showed good closeness (more than 94.86%). Good adsorption efficiency obtained for proposed methods indicates that, the 3A zeolite is capable to remove the significant amounts of Rhodamine B and Malachite green from environmental water samples.
本研究旨在探究3A分子筛作为一种新型吸附剂从水样中去除罗丹明B和孔雀石绿染料的效率。为提高去除效率，采用田口实验设计方法对吸附过程的影响参数进行了研究和优化。通过方差分析确定了各参数对罗丹明B和孔雀石绿染料去除率的贡献率，结果表明，3A分子筛去除RhB和MG最有效的参数分别是染料初始浓度和pH值。在优化条件下，田口设计方法预测值与实验值显示出良好的接近度（超过94.86%）。所提出方法获得的良好吸附效率表明，3A分子筛能够从环境水样中去除大量的罗丹明B和孔雀石绿。
