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.
