分光光度法测定食品中微量碘的研究
Study on the Spectrophotometric Determination of Iodine in Food
【摘要】 在HCl介质中,过量的Br2与I作用,余下的Br2对甲基橙具有褪色作用,且褪色的程度与I存在量有关,从而建立了快速光度法测定微量碘的新方法
【Abstract】 A spectrophotometric determination of micro amount iodide has been studied, based on the principle that the oxidation of 1 to I2 is completed by excess Br2, the remaiming part of Br2 reacts with methyl orange in hydrochloric acid medium.The de-colouration of solution was proportional directly to the amoant of I
