Abstract

The invention discloses a method for measuring sodium in sodium humate. By carrying out pretreatment with H2SO4-H2O2 in a temperature control type infrared digestion furnace and optimizing ICP-AES measurement parameters, the method for measuring the content of sodium in sodium humate by ICP-AES is established. The method has the advantages of being small in acid consumption, high in analysis speed, simple to operate and being relatively high in precision and accuracy and being suitable for analytic detection on the content of sodium in daily sodium humate.

Description

technical field [0001] The invention relates to a method for determining sodium in sodium humate. Background technique [0002] Humic acid is mainly the remains of animals and plants. It is a kind of complex natural organic substance formed and accumulated through a series of processes of microbial decomposition and transformation and geochemistry. Humic acid has been widely used in various fields such as agriculture, forestry, animal husbandry, petroleum, and chemical industry, spanning dozens of industries. Especially the current promotion of ecological agriculture construction, pollution-free agricultural production, green food, pollution-free environmental protection products, etc., makes humic acid highly respected. Facts have proved that human life and survival are inseparable from humic acid. [0003] At present, humic acid mainly exists in the market in two forms: humic acid and humate. Sodium humate is a kind of humate. It is chemically refined from high-quality l...
