| Abstract: | The cloud point extraction-UV spectrophotometry method was adopted to detect Cu2+ with glycine as a complexing agent,and the influential factors on the cloud point extraction efficiency of Cu2+ were investigated.The optimum cloud point extraction conditions for Cu2+ were determined as follows:the detecting wavelength was 230 nm,the pH value was 9.0,the dosage of NaCl solution was 4.0 mL,the dosage of 50.0 mg·mL-1 of Triton X-100 solution was 1.0 mL and the extraction time was 10 min. |
