泥炭的一个重要指标是灰分含量。目前化验室分析灰分含量采用烧灰方法,这种方法耗时费力,测一个样品需8小时左右。本文介绍用低能X射线反散射方法测定泥炭的灰分含量。这种方法简单、快速、测一个样品仅需1分钟。测量结果与化学常规分析比较,平均标准偏差约为3％。 An important indicator of peat is ash content. Current laboratory analysis of ash content using the method of burning ash, this method takes time and effort, measured a sample takes about 8 hours. This article describes the determination of ash content in peat by low energy X-ray backscatter. This method is simple and fast, measuring a sample in just 1 minute. The measurement results were compared with the routine chemical analysis, with an average standard deviation of about 3%.
