摘要
为了分析复合肥料中总氮、有效磷、氧化钾、氯离子含量测定能力验证的结果,依据《复混肥料(复合肥料)》(GB 15063—2009)和复合肥料中总氮、有效磷、氧化钾、氯离子含量测定能力验证参加指导书对2份测试样品进行测定。结果表明,样品2019-A16-025的检测结果为总氮17.34%、有效磷17.64%、氧化钾13.53%、氯离子10.43%,样品2019-A16-693的检测结果为总氮17.12%、有效磷10.16%、氧化钾15.50%、氯离子12.23%。2个考核样品的测定结果均为满意,说明本实验室具备复合肥料中总氮、有效磷、氧化钾、氯离子的检测能力。
In order to analyze the proficiency test results of content determination of total nitrogen,available phosphorus,potassium oxide and chloride ion in compound fertilizer,according to Compound Fertilizer(Compound Fertilizer)(GB 15063—2009)and the work instruction of proficiency test of determination of total nitrogen,available phosphorus,potassium oxide and chloride ion in compound fertilizer,two test samples were determined.The results showed that in sample 2019-A16-025,the content of total nitrogen,available phosphorus,potassium oxide and chloride ion was 17.34%,17.64%,13.53%and 10.43%,respectively;in sample 2019-A16-693,the content of total nitrogen,available phosphorus,potassium oxide and chloride ion was 17.12%,10.16%,15.50%and 12.23%,respectively.The determination results of two samples were satisfactory and illustrated that the laboratory had the detection ability of total nitrogen,available phosphorus,potassium oxide and chloride ion in compound fertilizer.
