FIELD: chemistry. ^ SUBSTANCE: method involves preparation of a silver (I) solution, extraction of silver (I) using a membrane with immobilised dithizone, its subsequent separation from the solution, measurement of the analytical signal and evaluation of silver (I) content. The membrane used is a polymethacrylate matrix with immobilised dithizone. The analytical signal used is light absorption at (52030) nm, light coordinate or visual evaluation of colour intensity of the optical membrane. Content of silver is evaluated using a calibration curve, by an addition technique or a visual test technique. ^ EFFECT: increased sensitivity of analysis. ^ 6 ex, 2 tbl, 1 dwg |
