The present work was centred on the study of potassium ethylxanthate, EtX-K+, which displays a remarkable selectivity and is widely employed in the treatment of sulphide ore. It was synthesised in our laboratory and its characterisation was performed, alongside with purity assessment, by analytical assays (IR,UV) as well as by decomposition studies. In particular, we aimed to develop the polarography procedure: DC(tast) method coupled with a modern dropping mercury electrode. (SMDE) for the determination of EtX-K+, enabled us to obtain defined and reproducible anodic waves. The investigation was carried out in the presence of NaOH as a supporting electrolyte at pH 12.6 within a broad concentration range (2x10^(-6)-1x10^(-4) M). In a following stage, a flow injection analysis (FIA) system with amperometric detection with wall-jet type cells operated at -0.1 V fixed-potential was implemented. Fia-grams with reasonably reproducible peaks were generated, with a sample throughput capacity of 72 determinations/hour and detection limit is estimate in 0.16 ppm. |

A síntese foi feita no laboratório e a caracterizaçáo e pureza, além dos estudos de reaçoes de decomposiçáo, foram feitos com auxílio das técnicas analíticas (IR, UV). Procurou-se desenvolver a metodologia polarográfica DC(first) trabalhando com moderno eletrodo de mercúrio de gota estática (SMDE) para a determinaçáo do EtX-K+ , obtiveram-se ondas anódicas definidas e reprodutíveis, usando como eletrólito suporte NaOH, pH 12,6 e numa ampla faixa de concentracáo (2x10^(-6)- 1x10^(-4) M). Na etapa seguinte adaptou-se o método poi aro gráfico a analise por injeçáo em fluxo, FIA, com detecçáo amperométrica; trabalhando a potencial fixo de -0,1V, e usando uma célula tipo "wall-jet" feita no laboratório, foram obtidos fiagramas com picos bastante reprodutíveis; a freqüéncia da amostragem de 72 injeçoes/ hora; o limite de detecçáo foi estimado em O,16 ppm.Neste trabalho enfatizou-se o estudo do etilxantato de potássio, EtX-K+, por ser um reagente bastante seletivo e muito utilizado no tratamento de minerais sulfetados.
