四苯硼钠比色法测定窖泥钾含量，对不同的钾标准液浓度进行分段处理。结果表明：钾标准液浓度小于10mg/L时，其线性相关性较差，不符合朗伯比尔定律。在钾标准液浓度为大于等于10mg/L时，回归曲线线性良好，R2值达到0.9998，符合朗伯比尔定律。%Determination of potassium content in pit mud by sodium tetraphenylborate colorimetry and divide the potassium content of different concentrations of standard solution in segmentation process.The results showed that: When Potassium standard solution concentration is less than 10mg/L, their linear correlation is poor which does not meet the Lambert-Beer Law ,whlie the concentration of the standard solution of potassium greater than or equal 10mg/L, the regression curve with good linearity,and R2 value reached 0.9998, which in line with Lambert-Beer's law.
