Product Description：
Industries such as electroplating, chemical
processing, textile dyeing, battery manufacturing,
and metal fabrication generate zinc-containing
wastewater. Excessive zinc is harmful to human
health and may even pose carcinogenic
risks. Furthermore, using zinc-contaminated
wastewater for agricultural irrigation severely
impairs crop growth, particularly wheat. Excess zinc deactivates enzymes in soil, weakens microbial biological functions, and ultimately impacts human health through the food chain.
Product Principle：
This product employs spectrophotometric colorimetry for determination. After mixing the water sample with the conditioning agent, zinc in all forms is converted into zinc ions. In an alkaline environment and in the presence of a sensitizer, these zinc ions react with an indicator to form a colored complex. The analyzer detects this color change and converts it into a zinc value for output. The amount of colored complex formed corresponds to the zinc content.
