| Abstract: | This paper reports on the gas chromatographic method for the determination of free water in N.P.K.compound fertilizer.The absolute ethanol which has been dehydrated by a molecular sieve is used as extractant of free water in compound fertilizer,while GDX-401 is used as stationary phase,A thermal conductivity cell detector,and the external standard method for Quantitation are also employed.This method can be used to determine free water in the range of 0.2-1.0%. |
