本文对有机化合物转化为无机离子的几种方法进行了综述。采用间接法测量有机化合物中的卤素。并采用直接回流的方法将其转化为无机卤素离子，再用佛尔哈得法进行含量的测定。通过改变实验条件，得到了本实验测量卤素的最佳条件：加热回流时间：30～60min；酸度：0.1～1mol/L；加入的NaOH的浓度：20%（质量比）；测量氯时必须加入硝基苯或石油醚保护AgCl沉淀。测量结果的相对误差都在误差允许范围内，结果令人满意。
而有机物中磷的测定则采用磷钒钼黄光度法法对有机物中的磷含量进行测定。并通过改变实验条件，得到了本实验测量卤素的最佳条件：钼酸铵溶液在4～6ml之间吸光度值稳定，选用5ml；选用0.2%二硝基酚作指示剂；温度控制在15～25℃之间颜色稳定，显色反应须静置15分钟；在波长λ=440nm处进行吸光度测定。测量结果的相对误差都在误差允许范围内，结果令人满意。并分析了不确定度，其主要来源包括仪器的精密度、标准物质标称值的不确定度以及制备溶液过程中引起的不确定度，推导出各种传播系数表达式，计算出各种不确定度分量并将其合成。

麻烦各位牛人了,谢谢了啊!!!!!

In this paper, inorganic ions into organic compounds of several methods were reviewed. By indirect measurement of halogen organic compounds. And the use of direct return of their way into inorganic halogen ions, and then the Buddha HAMDOON properly carried out in the determination. By changing the experimental conditions, this was the best experimental halogen conditions: heating return time: 30 ~ 60 min; acidity: 0.1 ~ 1 mol / L; accession to the concentration of NaOH: 20% (ratio); measured by adding chlorine to be Nitrobenzene or petroleum ether protection AgCl precipitation. Measuring the results of the relative error in the error allowed within the framework of satisfactory results.
And organic phosphorus in the use of yellow phosphorus vanadium molybdenum method in organic law on the phosphorus content was measured. And by changing the experimental conditions, this was the best experimental halogen conditions: ammonium molybdate solution in 4 ~ 6 ml between the absorbance
