Formation of silver citrate/citric acid complexed solutions was investigated. Although, silver citrate is minimally soluble in water, it can successfully be dissolved in citric acid solutions. The maximum concentration of Ag(I) in solution is estimated at 23 to 25 g/L if the concentration of citric acid is at least 4 mol/L or higher. The dissolution of silver citrate in citric acid solutions was attributed to the formation of silver citrate complexes of a general formula [Ag(3)(C(6)H(5)O(7))(n+1)](3n-). The silver citrate/citric acid solutions, containing more than about 13 g/L Ag(+) ion, have exhibited a decrease in Ag(I) concentration in solution over time, due to crystallization. The crystallization product was attributed to the formation of [Ag(3)C(6)H(5)O(7)](x).nH(2)O. Importantly, the diluted silver citrate/citric acid complexed solutions have exhibited very strong bacteriostatic and bactericidal activities.

柠檬酸银配合物的合成及抗菌活性。

研究了柠檬酸银/柠檬酸络合溶液的形成。虽然柠檬酸银在水中的溶解度很小，但它可以成功地溶解在柠檬酸溶液中。如果柠檬酸的浓度至少为 4 mol/L 或更高，则溶液中 Ag(I) 的最大浓度估计为 23 至 25 g/L。柠檬酸银在柠檬酸溶液中的溶解归因于形成通式 [Ag(3)(C(6)H(5)O(7))(n+1)](3n- ）。由于结晶，含有超过约 13 g/L Ag(+) 离子的柠檬酸银/柠檬酸溶液显示出溶液中 Ag(I) 浓度随时间降低。结晶产物归因于形成 [Ag(3)C(6)H(5)O(7)](x).nH(2)O。重要的，
