A spectrophotometric method has been developed for determination of small amounts of silver dop�d in ceramic water filter candle using dithizone as a chromogenic reagent. The studies revealed that (i) the Amax of the Ag2-dithizonate complex Jay at 570 nm, (ii) the optical density was linear up to 10 ppm of silver, (iii) at pH 10-11 the complex was stable up to 4 hrs, above which it precipitated out, (iv) the alkaline dithizone solution retained its complexing property for a period of 6 hrs and (v) interferences due to AI, Fe, Ti etc were sequistered by adding EDT A and TEA prior to development of colour. Results obtained with the present method agreed well with those obtained by atomic absorption spectrophotometry. © 1985 Taylor & Francis Group, LLC.
