标准范围

在不影响煤的物质的条件下，用盐酸和氢氟酸处理煤样品，使其部分脱盐。记录酸处理造成的煤炭质量损失，并通过灰化部分脱矿质煤来确定矿物质的未溶解部分。测定灰中的铁含量，以便计算出萃取煤中的黄铁矿。此外，还测定了煤吸附的盐酸量。

A sample of the coal is partially demineralized by treatment with hydrochloric and hydrofluoric acids under such conditions that coal substance remains unaffected. The loss in mass of the coal due the acid treatment is recorded and the undissolved part of the mineral matter is determined by ashing the partiallay demineralized coal. The iron copntent of the ash is determined so that the pyrites present in the extracted coal can be calculated. In addition the amount of hydrochloric acid absorbed by the coal substance is determined.
