Product Features and Basic Model Specifications

Product Features

1. High Selective Adsorption: It has extremely strong selective chelating ability for nickel and cobalt ions. Even under the interference of 25g/L high-concentration ammonium ions, the adsorption capacity can still reach 30g/L, and the recovery purity is over 99.5%.

2. Excellent Regeneration Performance: It can be regenerated with 5-8% sulfuric acid as a regenerant, with regeneration efficiency over 95%, and the performance decay is less than 5% after multiple adsorption-regeneration cycles.

3. Good Chemical Stability: It is resistant to acid and alkali corrosion, and can be used stably in the pH range of 1-14.

4. Strong Anti-Pollution Ability: It can resist the interference of organic matter and oil in wastewater, and has a long service life.

Product Advantages

High-Efficiency Resource Recovery:

It can recover heavy metal resources such as nickel and cobalt from high-salt wastewater, and the recovered metal salts can be directly reused in production, reducing raw material procurement costs by 18% for enterprises.
Environmental Protection and Emission Reduction:

It can reduce the concentration of heavy metals in wastewater to below 0.1mg/L, meeting the national discharge standards.
Low Operating Cost:

The regeneration process is simple, with low requirements for equipment, reducing energy consumption and labor maintenance costs.
Broad Application Scenarios:

It is suitable for the treatment of various wastewater containing heavy metals, such as lithium battery ternary precursor production wastewater, electroplating wastewater, and metallurgical wastewater.

Primary Functions

1. Heavy Metal Ion Adsorption: Selectively adsorb heavy metal ions such as nickel, cobalt, copper, zinc, and lead in wastewater.

2. Resource Recovery: Regenerate the adsorbed heavy metal ions to obtain high-purity metal salts for reuse.

3. Wastewater Purification: Reduce the concentration of heavy metals in wastewater to meet the discharge standards.

Application Scenarios

1. Lithium Battery Industry: Recovery of nickel and cobalt resources from ternary precursor production wastewater.

2. Hydrometallurgy Industry: Separation and recovery of valuable metals such as copper, nickel, and cobalt from ore leachate.

3. Electroplating Industry: Treatment of electroplating wastewater to recover heavy metals such as chromium, nickel, and copper.

4. Environmental Protection Industry: Treatment of industrial wastewater containing heavy metals to reduce environmental pollution.

Precautions

1. Before use, the resin should be pretreated (soaked in acid and alkali) to remove impurities and activate the functional groups.

2. During the adsorption process, the flow rate of wastewater should be controlled to ensure sufficient contact time between the wastewater and the resin.

3. During the regeneration process, the concentration and flow rate of the regenerant should be controlled to ensure the regeneration effect.

4. The resin should be stored in a sealed, cool, and dry place to avoid moisture absorption and caking.
