摘要
根据GB 18877-2009,采用重铬酸钾容量法检测有机-无机复混肥料中的有机质,讨论在检测过程中,样品称样量、氧化剂加入量及水浴加热时间等因素对有机质检测结果的影响。实验表明,水浴加热时间的影响最为明显。
According to GB 18877-2009, organic matter in organic-inorganic mixed organic fertilizers was detected by potassium dichromate volumetric method. The effect of sample quantity, oxidizer addition and water bath calefaction time on the detection results, were discussed. Experiments showed that the effect of water bath heating time was the most obvious.
