Organic Sulfur-Based Heavy Metal Scavenger

I. Product Introduction

The organic sulfur-based heavy metal scavenger can effectively react with various heavy metal ions such as copper (Cu), chromium (Cr), lead (Pb), zinc (Zn), mercury (Hg), manganese (Mn), tin (Sn), nickel (Ni), cobalt (Co), antimony (Sb), cadmium (Cd), and bismuth (Bi) under ambient temperature and within a wide pH range. It quickly forms insoluble, low-moisture, easily filterable flocculent precipitates, enabling the efficient removal of heavy metals from wastewater.

II. Product Specifications

Chelation Strength Ranking (from strongest to weakest):
Hg²⁺ > Ag⁺ > Cu²⁺ > Pb²⁺ > Cd²⁺ > Zn²⁺ > Ni²⁺ ≈ Cr³⁺ > Fe²⁺ > Mn²⁺

III. Product Features

1. Strong Chelating Ability:
   Highly effective even in the presence of complexing agents and multiple heavy metal ions. Suitable for wastewater with high or low concentrations of heavy metals.

2. Easy to Use:
   Fully water-soluble and forms insoluble, low-moisture, easily filterable flocculent precipitates upon reaction.

3. Broad Compatibility:
   Reacts with various heavy metals (e.g., Hg, Cd, Zn, Cu, Ni, As, Fe, Co, Ag) to form insoluble compounds. Prevents re-release into the environment, making it an environmentally friendly solution.

4. Effective to Near-Zero Residuals:
   Proper dosage ensures that residual heavy metal concentrations can approach zero.

5. Excellent Storage Stability and Safe Handling.

IV. Usage Instructions

Lab-Scale Test Procedure:

1. Prepare 500–1000 mL of the heavy metal-containing wastewater in a beaker.

2. Add the heavy metal scavenger (theoretical dose: 100–200 mg per liter of wastewater; actual dosage typically 2–3 times higher, depending on wastewater complexity).

3. Stir for 5–10 minutes for thorough mixing and reaction.

4. Allow enough time for chelation and precipitation.

5. Add a suitable coagulant and flocculant (e.g., PAM).

6. After coagulation and settling, analyze the treated water.

7. Separate the flocculent precipitate from the water, ensuring compliance with discharge standards.

On-Site Application:

• Can be dosed continuously or in batches.

• Dosage and process conditions should be based on lab-scale results.

• Ensure thorough mixing with wastewater for 10–15 minutes.

• Solid-liquid separation (e.g., sedimentation, filtration) can be used industrially.

• Higher dosage leads to lower residual heavy metals, but for cost-effectiveness, the optimal dosage should be determined experimentally and adjusted during use.
