The concentration of the free ligand in the extract decreases with time; this decrease obeys good first-order kinetics, and depends on the acidity. On the other hand, the concentration of Cu(PCD)_2 is not seemingly altered as long as the free ligand is present in the extract; however, the copper chelate begins to react with hydrochloric acid as soon as the free reagent has run out due to its decomposition. Furthermore, the reaction of Cu(PCD)_2 with hydrochloric acid in IBMK solution has also been studied kinetically. To monitor the reaction, the molar absorption coefficients of some species [CuCl(PCD), CuCl_2, and CuCl^-_3], which are formed in the course of this reaction, at 350 - 500 nm are determined. It can be thought that the reaction consists of not only simple ligand substitution by Cl^- but also of the path which gives CuCl(PCD) by reaction between Cu(PCD)_2 and CuCl_2,, and the path can be regard as the practical motive force of the decomposition of Cu(PCD)_2 extracted from hydrochloric acid solution.","subitem_description_type":"Other"},{"subitem_description":"紀要論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球大学理学部"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_1551255818386":"eng"}]},"item_1617186783814":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/20.500.12000/5376"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0286-9640"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN00250774"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球大学理学部紀要"},{"subitem_1522650068558":"en","subitem_1522650091861":"Bulletin of the College of Science.
