原始语种摘要: Objective: Chelating therapy is a medical procedure that involves the administration of chelating agents to remove heavy metals from the body; chelating agents detoxify heavy metals and toxins, converting them to inactive forms which were excreted out from the body. This work demonstrates the complication of the drug with toxic heavy metal lead (Π) ion. Methods: All the experiments were performed at different temperature (303, 308, 313, 318, and 323) °K, by spectrophotometric method. The electronic spectra of the mixture of drug and lead ion show a bathochromic (red) shift in ʎmax, the absorbance change caused by a complex arrangement between the lead ion and drug. Results: The stoichiometry of the complex formed was calculated using continuous variation method, it was found (1:2) that...
