Total organic chlorine

The methods of analysis for the chlorinated hydrocarbons may be divided into five classes—determination of total organic chlorine, determination of hydrolyzable or labile chlorine, colorimetric methods, physical methods, and bioassays. The last mentioned is beyond the scope of this manuscript and is not considered. 

Chemical analysis, including group variables like absorbable organic halogenids or total organic chlorine. 

Total organic chlorine in the rainwater was 0.3 p.p.b., with atrazine and the 2,4-D ester amounting to about 0.1 p.p.b. each. Since the soil one mile away contained 6 p.p.m. of atrazine, it can be calculated that no more than 16-17 mg. of soil per liter of rainfall would be sufficient to yield the 0.1 p.p.b. of atrazine actually found in the rain, and 16 to 17 mg. of suspended solids in a rain sample is not unusual.

A method for the determination of total organic chlorine content of water was described (121), based on the combustion of organic compounds to produce HCl which was subsequently detected with a crystal coated with amine 220. The reported detection limit was in the order of 100 pg of HCl, and 3 ppb of chloroform were detectable in a 100 fjl aqueous sample.
