Abstract
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. Keyword: Calcichrome, Stoichiometry, Mole ration method, Continuous Variation method, Selective reagent.

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
