Product Code ::RXSOL-60-6206-050
Categories: Lab Chemical-60
Product Short Description: We also have ready stock of Colour code pH Buffers 1.68, 4.01, 7.00, 6.86, 9.18, 10.01, 12.45
Product Description:
Total chlorine reacts with the potassium iodide solution and oxidizes the iodide to iodine. Both the iodine and the free chlorine react with DPD (N,N-diethyl-p-phenylenediamine)- colour solution to form a highly intensive pink coloured complex. The absorption is measured at a wavelength of 510. nm.
Product Application:
Analysis steps
The analysis vessel is cleaned and filled with fresh sample. After sampling the initial absorbance value is measured at 510 nm. Next, the potassium iodide, the colour solution and buffer solution are added and after respecting a stirring period – performed to obtain complete colour development – the final absorbance value is determined. With the obtained absorbance values, the total chlorine concentration can be calculated according to Beer’s law.
Product Dose:
Calibration
The calibration procedure measures a REF1 Cl2 solution (channel 9, REF1 valve) and a REF2 Cl2 solution (channel 10, REF2 valve) to adapt the slope and offset factors by means of a two-point calibration. The calibration is performed in the MAIN method.
Product Note:
Remark
The methods cannot be started at the same time.
