The result obtained by this analysis depends on factors such as:the degree to which the leather is ground;the extraction temperature;the extraction period;the ratio of leather to water.To obtain comparable results, it is consequently imperative that test conditions should be accuratelyreproduced.In all cases, any ammonium salts in the filtrate are included as part of the water-soluble matter and are thendecomposed on ignition. Thus they contribute towards the result for water-soluble organic substances. Theconcentration of the ammonium salts can be determined in the filtrate separately if required.【中国标准分类号】: Y46【国际标准分类号】: 59_140_30【页数】: 5P;A4【正文语种】: 英语
