を可能ならしめた。 A method for continuously analyzing total iron in sample water using the apparatus of the present invention in the above configuration will be described below. The sampling nozzle 12 is attached to the pipe 11 of the plant through which the sample water flows, with the sample suction port 12A facing the flow of the sample water correctly, and the tightening jig 13 is attached.
Fix it with. When collecting a sample, use the sample suction pump 3, chemical injection pump 8A, and flow rate adjustment pump 8E.
By simultaneously driving the sample water, the sample water is sucked into the sample inlet 14A of the connector 14 via the sample suction port 12A of the sampling nozzle 12, the sample discharge port 12B. In the connector 14, a constant flow rate of hydrochloric acid (concentration: 6 normal) is continuously injected from the hydrochloric acid inlet 14B via the chemical injection pump 8A and the line L1 . On the other hand, the suction flow rate of the sample suction pump 3 is set to twice the flow rate of hydrochloric acid. As a result, the sample water passes from the sample inlet 14A of the connector 14 to the total iron analysis sample outlet 14C, and then passes through the heating dissolution tank 5.
is attracted to. In addition, when analyzing other components such as hydrazine and ammonia in the sample water, the flow of the sample water is branched at the branch path of the connector 14, and the sample water can be fractionated through the sample discharge port 14D for analyzing other components. However, if analysis of other components is not required, close the on-off valve 16 or use a connector that does not have a sample discharge port 14D for analyzing other components. In addition, the sample outlet 14E of the connector 14
Although the excess sample is always discharged from the sampling nozzle 12, if the flow rate of the sample water in the sample suction port 12A of the sampling nozzle 12 is slow, the flow rate of the sample water collected is increased by the flow rate adjustment pump 8E. Next, a mixed solution of sample water and hydrochloric acid (hydrochloric acid concentration: 3 normal) exited from the total iron analysis sample outlet 14C of the connector 14.
enters a heating melting tank 5 set at around 105° C. via a conduit 4, where the colloidal iron is melted into ionic form. The mixed liquid of sample water and hydrochloric acid leaving the heated dissolution tank 5 is cooled down to room temperature by a cooler 15, and then introduced into the iron analyzer 10 via the suction pump 3. The mixed liquid sent to the reaction system is segmented by air bubbles sent through the air pump 8D. Hydroxylamine hydrochloride and ammonium acetate are then added to the mixture via dosing pump 8B and line L4 to reduce iron in mixer 6B and reduce the pH.
After adjusting the temperature to 4 to 5, add the TPTZ solution via chemical injection pump 8C and line L 3 , and add the TPTZ solution to mixer 6C.
to cause a color reaction with iron ions, and measure the absorbance of the blue chelate compound that changed color depending on the iron concentration using a colorimeter 7 to quantify the iron content.
are recorded continuously. The mixed liquid is temporarily segmented by air bubbles, but after the air bubbles are removed in the colorimeter 7, the absorbance is measured, resulting in a continuous chart. The analysis results using the device of the present invention are equivalent to the analysis values determined by the JIS B8224 total iron analysis method, and recorder charts that are adapted to changes over time are obtained. Continuous analysis of total iron in water was made possible.
