将邻氨基苯甲酸共价偶联到聚乙烯醇基质上,制得一个基于荧光碰撞猝灭机理的测定Fe~(3+)的光导纤维化学传感器.此传感器响应速度仅为90ms,且可逆性好.用它测定铝合金中的铁含量,取得满意的结果.
The anthranilic acid was covalently coupled to a polyvinyl alcohol matrix to prepare an optical fiber chemical sensor for the determination of Fe 3+ based on the fluorescence quenching mechanism. The sensor response speed was only 90 ms and the reversibility Good use it to determine the iron content of aluminum alloy, and achieved satisfactory results.
