The sugarcane trash ash (STA) has been explored as low cost adsorbent for atrazine and fipronil removal from water. Kinetics study suggested that the pseudo second order model best explain the adsorption of both pesticides. The STA show higher adsorption of fipronil (K_d - 1267.5-3321.1) than atrazine (K_d - 137.0-1445.3) while desorption followed reverse trend with 0-2.27 and 4.83-9.32% fipronil and atrazine desorption, respectively. Isotherm model optimization suggested that the Freundlich isotherm best predict the adsorption-desoprtion behaviour of pesticides. Adsorption is highly nonlinear as 1/n values were 0.23 and 0.407 for atrazine and fipronil respectively. Adsorption decreased with increase in initial concentration of pesticide in solution. The sugarcane trash, a waste, can be used as energy source in boilers and the ash obtained can be utilized as low-cost adsorbent for pesticide removal from contaminated water.

甘蔗垃圾灰：用于从水中去除for去津和氟虫腈的低成本吸附剂

甘蔗垃圾灰（STA）已被研究为低成本的吸附剂，可从水中去除at去津和氟虫腈。动力学研究表明，伪二级模型可以最好地解释两种农药的吸附。STA显示对氟虫腈（K _d -1267.5-3321.1）的吸附高于阿特拉津（K _d-137.0-1445.3），而解吸则出现相反的趋势，分别为0-2.27和4.83-9.32％的氟虫腈和at去津解吸。等温线模型优化表明，Freundlich等温线最能预测农药的吸附-脱附行为。吸附是高度非线性的，因为at去津和氟虫腈的1 / n值分别为0.23和0.407。吸附随着溶液中农药初始浓度的增加而降低。甘蔗垃圾（一种废物）可以用作锅炉的能源，而获得的灰烬可以用作低成本的吸附剂，用于从污水中去除农药。
