Role of octanol–water partition coefficients in extraction of ionisable organic compounds in a supported liquid membrane with a stagnant acceptor

摘要: Abstract The correlation between the logarithm of octanol–water partition coefficients (log  K ow ) and in di- n -hexyl ether–water -undecane–water D which are used as organic solvents a supported liquid membrane extraction method with stagnant acceptor was studied for group 17 s -triazines. A linear relationship log  found. plot efficiency obtained their above compounds together phenoxyacids, phenols local anaesthetics resulted into an approximately bell-shaped relationship. Maximum those values ∼3.0. Those high were easily dissolved but difficulty to strip solution, thus giving lower efficiency. In contrast, low gave due poor dissolution liquid. Implications on analytical application SLM technique discussed.
