Heavy Metal Capture Agent
Heavy metal capture agents are chelating polymers that selectively bind with heavy metal ions (Cu, Ni, Zn, Cr, Pb, Cd, Hg) to form stable, insoluble complexes that can be removed by sedimentation or filtration.
Target Metals
- Copper (Cu), Nickel (Ni), Zinc (Zn)
- Chromium (Cr3+, Cr6+)
- Lead (Pb), Cadmium (Cd), Mercury (Hg)
- Arsenic (As)
Features
- Residual metal below 0.1 mg/L achievable
- Works across pH 3-11
- No secondary pollution — stable precipitate
- Compatible with existing treatment systems
Especially suitable for electroplating, PCB manufacturing, and metal finishing wastewater.
Typical Applications
- Electroplating and surface finishing wastewater
- PCB, electronics, and metal processing wastewater
- Mining, leachate, and chemical wastewater containing heavy metals
- Polishing treatment after pH adjustment, coagulation, and precipitation

FAQ: Heavy Metal Capture Agent
Which heavy metals can this product help remove?
It is commonly used for wastewater containing copper, nickel, zinc, lead, cadmium, mercury, chromium, and other heavy metal ions. The final removal result depends on the water matrix and process conditions.
Is pH adjustment still required?
In most treatment systems, pH control is still important. The capture agent is often used after pH adjustment and before solid-liquid separation to improve heavy metal precipitation and stability.
Can it replace PAC or PAM?
No. Heavy metal capture agent targets metal ions. PAC and PAM are still commonly used for coagulation, floc growth, clarification, and sludge dewatering.
What documents can be provided before testing?
COA, MSDS, product specification, packaging information, and sample arrangement can be provided for buyer review before trial dosing or bulk purchase.
