摘要
本研究通过紫外/可见光谱和红外光谱分析证实了配体钙铬酸盐在pH为8.5时与钙离子形成稳定的配合物，并通过羟基进行络合。通过摩尔比法和连续变分法，发现所形成的络合物的化学计量比为1:1。配合物的干灰化法和火焰发射光度法分析表明，配合物中钙的含量为4.5%，由于实验误差，误差为2.41%。关键词:钙铬，化学计量，摩尔比法，连续变分法，选择性试剂。IHSCICONF 2017特刊Ibn Al-Haitham Journal for Pure and Applied science https://doi.org/ 10.30526/2017.IHSCICONF.1801有关会议的更多信息，请访问以下网站:http://www.ihsciconf.org/conf/ www.ihsciconf.org Chemistry |322
Spectrophotometric and Potentiometric Analysis of Calcichrome and Its Complex With Calcium Ion
It was confirmed in this research that the ligand calcichrome formed stable complex with calcium ion at pH of 8.5 which verified by UV/Vis and FTIR spectral analysis and the complexation occurred via hydroxyl groups. The stoichiometric ratio of the formed complex was found to be 1:1 by mole ratio and continuous variation methods. Dry ashing method of the complex and flame emission photometric analysis offered a calcium percentage in calcium complex equal 4.5% with an error of 2.41% due to experimental errors.
