摘要：
In this invention, a colorimetric method for the detection of ascorbic acid (AA) and tannic acid (TA) was disclosed. copper-rhodium nanomaterial (Rh-Cu nanozyme) can be an ideal oxidizer toward 3,3',5,5'-tetramethylbenzidine (TMB). The catalytic activity of Rh-Cu nanozyme depends on several variables such as concentration of enzyme, concentration of TMB, pH, temperature and so on. Ascorbic acid (AA) and tannic acid (TA) process strong reduction identity, which can directly reduce the oxidized TMB (oxTMB) to TMB, resulting color of the solution faded from blue to colorless. Thus, the quantitative presence of AA and TA can be obviously detected by the extent of changed color. In order to optimize the performance of this system to the biggest degree, the best conditions of variables were studied. With all these optimal conditions, this detection system can be an inexpensive and simple method to identify TA and AA in many cases, which will also be potentially beneficial to other technologies. The results present
