矿物源腐植酸肥料中可溶性腐植酸的测定方法研究

摘要

为适应矿物源腐植酸肥料的检测要求，以综合标准化为目标，对矿物源腐植酸肥料中可溶性腐植酸的测定方法进行了研究。通过对腐植酸肥料中可溶性腐植酸的称样量、提取时间、酸化沉淀条件等进行优化。对制定可溶性腐植酸测定的主要技术参数提出了具体工艺要求。%This paper discusses the determination of humic acid fertilizer on mineral source of soluble humic acid.To adapt to the mineral source of humic acid fertilizer testing requirements as a benchmark to comprehen-sive standardized as guidance to the modern scientific research as a basis for"mineral source of soluble humic acid fertilizer determination"methods were studied.By soluble humic acid fertilizer humic acid sample weight, the extraction time,acidification precipitation conditions were optimized.Experimental study on the develop-ment of the main technical parameters of soluble humic acid determination,made optimum requirements.
