ANALYSIS OF IODINE IN OFF-GAS

Title:

ANALYSIS OF IODINE IN OFF-GAS

Document Type and Number:

Japanese Patent JPH04278444

Kind Code:

A

Abstract:

PURPOSE: To simultaneously measure org. iodine and inorg. iodine in off-gas.

CONSTITUTION: The sample gas from off-gas piping 1 is collected to be stored in an irradiation cell 2. The sample gas in the irradiation cell 2 is irradiated with ultraviolet rays from an ultraviolet lamp 4 to decompose organoiodine in the sample gas. By this method, iodine in the sample gas entirely becomes inorg. iodine. This sample gas is sent to a fluorescence analyser 5 and the absolute amount of iodine is measured by the fluoresence analyser 5. By decomposing organoiodine by ultraviolet rays, organoiodine can be measured simultaneously with inorg. iodine.
