锰，是一种灰白色、硬脆、有光泽的金属，锰广泛存在于自然界中，土壤中含锰0.25%，茶叶、小麦及硬壳果实含锰较多。 Manganese is a grayish-white, hard-brittle, shiny metal. Manganese is widely found in nature. The soil contains 0.255% manganese. Tea, wheat and hard-shell fruits contain more manganese.
This product is measured by spectrophotometry. After mixing water and buffer, manganese is converted into high-valence ions in the presence of strong oxidant. In the presence of buffer solution and indicator, high-valent ions react with indicator. A colored complex, the analyzer detects the change in the color and converts the change into a manganese value output, and the amount of the colored complex formed corresponds to the amount of manganese.
