一、前言钙镁磷肥中磷的测定方法,一般厂采用钼酸喹啉容量法。这一方法较钼酸铵容量法和磷酸铵镁重量法都要准确快速,但是作为指导工艺生产的炉前分析来说,还是不够简便快速的。若采用磷钒钼黄比色法,在严格控制比色条件的情况下,测得结果的准确度和重现性很好。在分析速度上,全磷的分析 First, the preface Determination of phosphorus in magnesium magnesium phosphate method, the general plant with molybdate quinoline capacity method. This method is faster and more accurate than ammonium molybdate and magnesium ammonium phosphate gravimetric methods, but is not as quick and easy as a prefilter to guide process production. If phosphorus and vanadium molybdenum yellow colorimetric method, under the strict control of colorimetric conditions, the measured results accuracy and reproducibility is very good. Analysis of total phosphorus in terms of speed of analysis
