摘要
测定出在微乳介质中硫氰酸铁（Ⅲ）的显色反应热力学摩尔吸光系数，其数值在４８０ｎｍ处，当溶液离子强度趋近于１时ｌｏｇε°＝４．６７，对于海水一般含盐量为３２‰～３５‰的样品，采用热力学摩尔吸光系数表示光度分析的灵敏度有普遍意义．
The thermodynamical molar absorptivity of ferric-thio cyanatev complexes inmicromulsion medium has been determined in this work. The results show that when the ironstrength is near 1,logε°= 4. 67 at'the wavelength of 480 urn. And the determination method ofthe thermodynamical molar absorptivity by means of in this paper is of ordinary utility when theamount of salt concentvation is 33～37. 5 % in seawater.
