| Abstract: | In acidic medium,Fe2 reacts with orthophenanthroline and produces orange complex whose largest absorption wavelength is 510nm.A good linea spectrophotometric relation is shown in the Fe2 conceatration range of 0~130mg/ml,and the recovery is above 95%.The method is suitable for the measurement of micro-iron ion in ceramic raw materila. |
