What are the analysis items and parameters for the purification of acidic water used in hydrogen production?

The analysis items and parameters for purifying water used in hydrogen production mainly include: 1. pH value: Used to determine the acidity or alkalinity of the water. The pH value of acidic water is usually below 7. 2. Conductivity: Reflects the total amount of dissolved solids in water, and indirectly indicates the purity of the water quality. 3. Microbial indicators: such as total bacterial count and E. coli group, to ensure water quality safety. 4. Organic matter content: such as total organic carbon (TOC), etc., to assess the level of organic pollutants in water. 5. Heavy metal content: includes elements such as lead, mercury, and arsenic, all of which are harmful to the human body. 6. Content of inorganic ions such as chlorides and sulfates: affects the taste and purity of water. The limits for specific parameters are determined based on local water quality standards and specific application requirements. .
