COMPARISON OF ANALYTICAL RESULTS FOR TWO SAMPLING METHODS OF NITROGEN IN AMMONIA FROM OIL FIELD WATER
-
摘要: 油田水中氨氮取样采用了两种方法。对于同一样品,一种是现场直接取样进行密封;另一种对样品在现场用1:1H2SO4进行酸化,使水中的pH值在2以下。然后把样品带回实验室马上进行测定。其结果是同一样品不同的取样方法所测的氨氮值大有差别,酸化样所测得的氨氮值大大高于原样所得的值。Abstract: The data of nitrogen in ammonia from oil field water are very different by different sampling methods.If samples was preprocessed by 1:1H2SO4,the analytical results were much higher than the value of samples without preprocessing.
