摘要

提出了一种利用消费者光学光栅成像的数字比色法测定土壤样品中吲酚类染料铵的方法。该方法是基于分光光度法测定土壤中氯化钾提取后的铵。该技术确保了准确性，并提供了接近分光光度法的灵敏数字比色技术。通过分析在莫斯科州各区收集的标准样品和土壤样品，证实了所提出方法的充分性。

Colorimetric Determination of Ammonium in Soil Samples

A technique for determining ammonium as an indophenolic dye in soil samples by digital colorimetry using consumer optical means of obtaining raster images is proposed. The developed approach is based on photometric methods for determining ammonium after extraction from soil with potassium chloride. This technique ensures accuracy and provides sensitive digital colorimetric techniques close to spectrophotometric ones. The adequacy of the proposed approach is confirmed by analyzing the standard samples and soil samples collected in the districts of Moscow region.
