Method/Apparatus/Procedure:
A colorimetric method was used. A 2.5 g trichloromethane sample was pipetted into a centrifuge tube containing 20 cm
3
water. The tube was then vigorously shaken in a thermostat bath for 2 days. After shaking, the tube was centrifuged at high speed to give a clear upper water layer. From this layer the concentration of trichloromethane was determined by using a colorimetric method.
