Product Overview:
Nickel is a silver-white metal with a hard and brittle texture. It remains stable in air at room temperature and is a relatively inactive element. Nickel reacts readily with nitric acid, while its reaction with dilute hydrochloric or sulfuric acid is slower. Nickel occurs naturally in various ores, often combined with sulfur, arsenic, or antimony, and is primarily sourced from minerals such as chalcopyrite and pentlandite. It may be present in wastewater from mining, smelting, alloy production, metal processing, electroplating, chemical industries, as well as ceramic and glass manufacturing.
This analyzer is capable of operating automatically and continuously without long-term manual intervention based on field settings. It is widely applicable for monitoring industrial pollution discharge wastewater, industrial process wastewater, industrial sewage treatment plant effluent, and municipal sewage treatment plant effluent. Depending on the complexity of the on-site testing conditions, a corresponding pretreatment system can be optionally configured to ensure reliable testing processes and accurate results, fully meeting the needs of various field scenarios.
Product Principle:
This product utilizes the spectrophotometric measurement method. After the water sample is mixed with a buffer agent, and in the presence of a strong oxidizing agent, nickel is converted into its higher valence ions. In the presence of a buffer solution and an indicator, these higher valence ions react with the indicator to form a colored complex. The analyzer detects this color change, converts the variation into a nickel concentration value, and outputs the result. The amount of colored complex generated corresponds to the nickel concentration.
