The disagreeable odor of the pyridine, the lower stability and reproducibility of the complex are justifications for many works related to the alternatives of the method. The SDDC/pyridine system was substituted for system using triethanolamine 5% v/v in chloroform with many advantages. The method was used for arsenic determination in hair samples with good recovery. Many kinds of digestions was studied.porAcesso AbertoMetais pesadosArsênioEspectrofotometriaDitiocarbDietilditiocarbamato de prataTrietanolaminaCabeloDeterminação espectrofotométrica do arsênio em cabelo usando o método do dietilditiocarbamato de prata (SDDC) e trietanolamina/CHCl3 como solventeFlow injection spectrophotometric determination of phenolic compounds in wastewaters using peroxidase of zucchini (Cucurbita pepo)Artigo de Periódico
