| titleOfInvention | Automatic analysis method of formaldehyde in water sample |
| abstract | The invention discloses an automatic analysis method of formaldehyde in a water sample. The automatic analysis method comprises the following steps of: enabling a mixed solution of a test sample S1, reaction liquid R2 and a reference solution R0 to enter an optical flow cell by adopting a negative-phase reference flow injection method; transmitting a signal to a computer processing system for processing by an optical detector to obtain a base line, a standard sample or a test sample which is mixed with the reaction liquid R2 and a chromogenic solution R1 to generate chromogenic reaction; and enabling the formed chromogenic mixed solution to enter the optical flow cell, and transmitting the signal to the computer processing system for processing by the optical detector to obtain a standard sample spectrogram or a test sample spectrogram; and calculating the content of formaldehyde in the test sample by a regression equation of a standard sample working curve according to the peak height of the test sample spectrogram, wherein the chromogenic solution R1 is an ammonium ferric sulfate-hydrochloric acid aqueous solution; the reference solution R0 is hydrochloric acid aqueous solution; the reaction liquid R2 is a phenol reagent aqueous solution. The analysis apparatus comprises a sample flow path with a cation exchange column, a reference solution flow path, a chromogenic solution flow path, a reaction liquid flow path, an analysis flow path and the computer processing system. |
