合成了铁酸锌(ZnFe2O4)和铁酸铜(CuFe2O4)纳米颗粒,和特点,这些材料用于去除茜素黄R(AYR)的有机染料,噻唑黄G(TYG),刚果红(CR),通过吸附技术从工业废水中提取甲基橙(MO)。通过化学共沉淀法合成了ZnFe2O4和CuFe2O4。使用XRD对这些纳米材料的物理化学性质进行了表征,FTIR,BET,VSM,DLS,Zeta电位,和FESEM-EDX分析仪器。ZnFe2O4和CuFe2O4的BET表面积分别为85.88m2/g和41.81m2/g,分别。吸附影响参数,包括溶液pH值的影响,吸附剂数量,染料污染物的初始浓度,并检查了接触时间。溶液的酸性介质有利于废水中染料的较高去除百分比。出于不同的等温线,Langmuir平衡等温线显示出与实验数据的最佳拟合,表明在处理过程中单层吸附。发现ZnFe2O4的最大单层吸附容量为54.58、37.01、29.81和26.83mg/g,而AYR的CuFe2O4的最大单层吸附容量为46.38、30.06、21.94和20.83mg/g,TYG,CR,和MO染料,分别。从结果的动力学分析,推断,伪二级动力学与较好的测定系数(R2)值拟合良好。观察到使用ZnFe2O4和CuFe2O4纳米颗粒通过吸附技术从废水中去除四种有机染料是自发的和放热的。从这次实验调查来看,已经推断,磁性可分离的ZnFe2O4和CuFe2O4可能是从工业废水中去除有机染料的可行选择。
Nanoparticles of zinc ferrite (ZnFe2O4) and copper ferrite (CuFe2O4) were synthesized, and characterized, and these materials were applied for removal of organic dyes of alizarin yellow R (AYR), thiazole yellow G (TYG), Congo red (CR), and methyl orange (MO) from industrial wastewater through adsorption technique. Synthesis of ZnFe2O4 and CuFe2O4 was achieved through chemical co-precipitation method. These nanomaterials were characterized for physicochemical properties using XRD, FTIR, BET, VSM, DLS, Zeta-potential, and FESEM-EDX analytical instruments. BET surface areas of ZnFe2O4 and CuFe2O4 were 85.88 m2/g and 41.81 m2/g, respectively. Adsorption-influencing parameters including effect of solution pH, adsorbent quantity, initial concentration of dye pollutant, and contact time were examined. Acidic medium of the solution favored higher percentage of removal of dyes in wastewater. Out of different isotherms, Langmuir equilibrium isotherm showed the best fit with experimental data, indicating monolayer adsorption in the treatment process. The maximum monolayer adsorption capacities were found as 54.58, 37.01, 29.81, and 26.83 mg/g with ZnFe2O4, and 46.38, 30.06, 21.94, and 20.83 mg/g with CuFe2O4 for AYR, TYG, CR, and MO dyes, respectively. From kinetics analysis of the results, it was inferred that pseudo-second-order kinetics were fitting well with better values of coefficient of determination (R2). The removal of four organic dyes from wastewater through adsorption technique using nanoparticles of ZnFe2O4 and CuFe2O4 was observed to be spontaneous and exothermic. From this experimental investigation, it has been inferred that magnetically separable ZnFe2O4 and CuFe2O4 could be a viable option in removal of organic dyes from industrial wastewater.
