An excellent composite was synthesized for sorption of strontium from solution. The composite (CuHCNPAN) components were copper hexacyanoferrate, magnetite and PAN. The XRD method confirmed the formation and presence of two crystalline phases of magnetite and copper hexacyanoferrate in composite. Particle sizes were determined by XRD and SEM methods. It was found that the particles were nano size. Some other methods such as FT IR, BET and TG methods were also used to determine the properties of the composite.

The composite was used for sorption of strontium from solution. It was found that the kinetic of strontium sorption by the composite could be modeled by pseudo-second order. Among the isotherms applied to modeling the sorption in various concentrations, the Langmuir isotherm was founded to be more appropriate to fitting the experimental data. An excellent correlation coefficient was obtained (R₂ > 0.98). The q_max for sorption of strontium ions which was calculated by Langmuir model was 80 mg/g. The thermodynamic parameters were calculated by determination of sorption in various temperatures and using the Vant Hoff plot. ΔG°, ΔH◦, and ΔS◦ were calculated as −19.15, 2.28 and 0.071 kJ/mol respectively.

合成了一种优异的复合物，用于从溶液中吸附锶。复合材料（CuHCNPAN）成分是六氰合铁酸铜，磁铁矿和PAN。XRD法证实了复合物中磁铁矿和六氰合铁酸铜的两个晶相的形成和存在。粒度通过XRD和SEM方法确定。发现颗粒是纳米尺寸的。还使用其他一些方法（例如FT IR，BET和TG方法）来确定复合材料的性能。

该复合物用于从溶液中吸附锶。研究发现，复合材料对锶的吸附动力学可以用伪二级模拟。在用于模拟各种浓度吸附的等温线中，Langmuir等温线被认为更适合拟合实验数据。获得了极好的相关系数（R ₂  > 0.98）。通过朗缪尔模型计算出的锶离子吸附的q _max为80 mg / g。通过确定在各种温度下的吸附并使用Vant Hoff图来计算热力学参数。ΔG°，ΔH◦和ΔS◦分别计算为-19.15、2.28和0.071 kJ / mol。
