    In a typical reaction, the salt of calcium was dissolved in 2:1 mixture of methanol and distilled water , then 0.15 g of sodium 2-mercaptobenzothiazole was added to the reaction mixture and the resultant reaction mixture was stirred for 1 h at 70 C°. After 1 h, solution of 1,10-phenanthroline was added to the reaction mixture and stirred for 2 h.
