主次双波长计算光度法测定铁的研究——phen—Fe(Ⅱ)显色体系测定水中铁

Study of Determination of Iron With Primary-Secondary Wavelengths Computation——phen-Fe(Ⅱ) chromogenic system determinaced iron in water

本文利用主次双波长光度法 ,通过Fe(Ⅱ )—phen显色体系 ,依据显色体系吸光度A与照射波长λ及物质浓度x间的关系 ,提出了测定铁的主次波长新光度法 ,精密度提高 。

New method determination by primary-secondary wavelengths with Fe(Ⅱ)-phen chromogenic reaction system has been introduced.The method is to have precision higher and detection limits lower.
