摘　　要：研制出了一种新的流动比色装置(FIA),不需要增加任何辅助设备,一次进样同时可连续获得两峰一谷3个吸光度值,均可以用于定量分析。利用吸光度加和技术,使分析装置的灵敏度得到大幅度的提高。对其理论和实验技术进行了研究和尝试,并用于铝合金中铜的测定,实验结果令人满意。The new FIA device was studied. By using the device, two peaks and a valley were obtained without other supplementary device. The detection sensitivity was improved highly with absorbency addition technology. The determination result of the copper in aluminum alloy by this device was satisfactory.
