| titleOfInvention | The detection method of lemon chrome concentration in one heavy metal species high alkali liquid body |
| abstract | The invention discloses the detection method of lemon chrome concentration in a heavy metal species high alkali liquid body, the method is using the heavy metal concentrated base liquid of different lemon chrome concentration as test sample, obtain each test sample Raman spectrum when setting in wave-number range with silicon chip as substrate, and according to the Raman spectrum of all test samples, it is respectively adopted successive projection algorithm and multi-element linear regression method determines calibration wave number, in lemon chrome concentration according to each test sample, and corresponding Raman spectrum, the peak at each calibration wave number is strong and 520cm ‑1 The strong ratio in peak at place builds the linear regression model (LRM) of concentration strengths ratio as calibration model, utilizes calibration model measurement to obtain the concentration of lemon chrome in sample to be tested.Raman test is utilized to be analyzed, simple to operate, it is not necessary to carry out loaded down with trivial details, time-consuming Sample Preparation Procedure, the interference simultaneously avoiding other sources and then the accuracy of the lemon chrome that ensure that test, and the accuracy of test is substantially increased as a comparison with silicon. |
