Continuous Method for Determination of Mercury in Exhaust Gas

説明

We developed a continuous method of mercury measurement in exhaust gas from stack. The outline of this method is as follows: after specified pre-treatment of using reducing agent (SnCl₂), sample gas is continuously introduced into analytical quartz cell and then analyzed by cold vapor atomic absorption technique. We investigated the accuracy of this method and the adaptation for thesample. gas from municipal refuse incinerator. The results were as follows. 1. The linearity was less than 2% till mercury concentration 3.0mg/m³ in case ofusing 10cm cell length. 2. 90% response time was about 20 second. 3. The influence by interference gases can be neglected. 4. Regression line between this continuous method (y) and wet absorption method (x) used KMnO4 and H₂SO₄ can be described as follows; Y=1.08X+0.01. The coefficient of correlation was 0.988. As a result of this studies, it became clear that this continuous method can be applied to measure mercury in exhaust gas.
