【摘要】 研究了以阳离子交换树脂为显色载体 ,利用直接吸附在树脂上有色络合物———Fe(Ⅱ )邻二氮菲的吸光度 ,借以检测水和火腿肠中铁的新方法。本法具有比原子吸收法更高的灵敏度、稳定性和选择性 ,并对成络及树脂吸附条件作了较详细研究更多还原

【Abstract】 Using positive ion as color carrier and the absorbance of nonferrous complex compound ferrum(Ⅱ) absorpted at the resin,ferrum in water and ham is detected by a mew method.The method has higher sensitivity,stabitity and selectivity than atomic absorption method and the conditions of absorption are sutdied.更多还原
