SIMPLE AND SENSITIVE DETECTION FOR TRACE CHROMIUM (VI) USING ALBUMIN AS FLUORESCENCE PROBES

We have developed a novel method for fast determination of chromium(VI) using egg albumin(EAB) as fluorescence probe. The influence factors, including pH, reaction time, concentration of EAB, were investigated on the performance of the method and the optimum experimental conditions were determined....
