Method/Apparatus/Procedure:
A mixture of 1 cm3 trichloromethane and 30 cm3 water was introduced into a centrifuge tube which was then shaken for 60 minutes in a shaker at room temperature. After an additional shaking of 48 hours, samples were filtered through four types of filter paper in order to free the solution from emulsions. The concentrations of the aqueous solutions were determined by the TOC (Total Organic Carbon) method. Nine measurements were performed for each solution.
Source and Purity of Materials:
- Tokyo Chemical Co., analytical grade reagent, redistilled before use.
- Double distilled.
Estimated Errors:
Ambient temperature: ±1.0 K.
Mass concentration (m/v) (1): 0 - 2.5% coeff. of var.
