Eco-Friendly Soil Remediation: Why Tetrasodium Iminodisuccinate (IDS) is the Future of Heavy Metal Removal

In the global effort to restore contaminated lands, Soil Washing has emerged as a rapid and cost-effective methodology. However, the industry faces a critical dilemma: traditional chelating agents like EDTA are persistent in the environment, often causing secondary pollution.

YuanlianChemical is proud to introduce a sustainable breakthrough—Tetrasodium Iminodisuccinate (IDS). As a high-performance, biodegradable complexing agent, IDS offers a powerful yet "green" alternative for the remediation of Cu, Pb, and Cd contaminated soils.

The IDS Advantage: Performance Meets Sustainability

Unlike conventional chemicals, YuanlianChemical’s IDS is designed to balance technical efficiency with environmental safety.

Key Benefits:

• Rapid Biodegradability: IDS breaks down naturally in soil, eliminating the risk of long-term chemical persistence.

• High Chelation Stability: Exhibits strong affinity for toxic heavy metals including Copper (Cu), Lead (Pb), and Cadmium (Cd).

• Superior Solubility: Dissolves easily in aqueous solutions, ensuring uniform distribution during the soil washing process.

• Non-Toxic Profile: Minimizes the ecological footprint on soil microbiota compared to traditional amino carboxyl chelants.

Technical Insights: Optimized Remediation Parameters

Extensive research and project data from YuanlianChemical identify the optimal conditions for maximizing heavy metal extraction using IDS.

Optimal Operating Conditions:

Proven Results: Under these optimal settings, IDS achieved removal rates of 80.6% for Cu, 71.1% for Pb, and 59.1% for Cd in simulated contaminated environments.

Field Case Study: Shanghai Pb-Polluted Site

The efficacy of YuanlianChemical IDS is not limited to laboratories. In a real-world project involving a lead-polluted field in Shanghai, IDS demonstrated exceptional performance:

• Initial Pb Concentration: 460 mg · kg⁻¹

• Post-Treatment Concentration: 86.8 mg · kg⁻¹ (Mean Value)

• Regulatory Compliance: The final levels fell significantly below the strict "Residential Area" threshold (140 mg · kg⁻¹) required by the Risk Assessment of Soil Environmental Health in Shanghai.

Even at a reduced concentration of 4.5 mmol · L⁻¹, IDS effectively restored the soil to safe, usable standards.
