Mixed bed resin was prepared using T-46 (H⁺) and A-33 (OH⁻) through mixing their ratio 1: 1.6 and characterized by Fourier transform infrared scanning electron microscopy and energy dispersive X-Ray spectroscopy. The mixed bed resin was evaluated for the removal of cesium and strontium from contaminated water. The aim of our study was to find the suitable condition for removal of Cs and Sr ions from water under different conditions viz. initial concentration of Cs and Sr ions, contact time, dose of resin and pH. Cs and Sr ions, adsorption data are fitted well with Freundlich and Langmuir isotherm models. The adsorption capacity was 7.53 and 9.58 mg/g for Cs and Sr ions, respectively as obtained at initial concentration 10 mg/L by Langmuir isotherm. Adsorption kinetics was followed by pseudo-second order reaction. The rate constants of pseudo-second order reaction were calculated and quite high correlation coefficients R² 98–99.5 were obtained. The resin also used for removal of Cs and Sr ions from tap water (TDS—200 mg/L) and saline water (TDS—2000 mg/L), and showed 90% (Cs) and 95% (Sr) removal at 10 mg/L of each ion concentration.

树脂从水溶液中去除Cs +和Sr 2+的吸附和动力学研究

使用制备混合床树脂的T-46（H ⁺）和A-33（OH ^-），以1：1.6的比例混合并通过傅立叶变换红外扫描电子显微镜和能量色散X射线光谱进行表征。评估混合床树脂从污染水中的铯和锶的去除。我们研究的目的是找到在不同条件下从水中去除Cs和Sr离子的合适条件。Cs和Sr离子的初始浓度，接触时间，树脂剂量和pH。Cs和Sr离子的吸附数据与Freundlich和Langmuir等温线模型拟合得很好。由Langmuir等温线在初始浓度10 mg / L下获得的Cs和Sr离子的吸附容量分别为7.53和9.58 mg / g。吸附动力学之后是假二级反应。获得R ² 98-99.5。该树脂还用于去除自来水（TDS-200 mg / L）和盐水（TDS-2000 mg / L）中的Cs和Sr离子，在10℃时显示出90％（Cs）和95％（Sr）的去除每个离子浓度mg / L。
