How to choose sodium persulfate for oil contaminated site remediation?

In the remediation of petroleum-contaminated sites, sodium persulfate as an efficient oxidizing agent serves as a key material in chemical oxidation remediation. Its product quality and supply stability directly determine the success of remediation projects. Scientifically selecting high-quality sodium persulfate is essential for achieving remediation goals efficiently and economically.

I. Key Considerations for Selecting Sodium Persulfate in Petroleum Contaminated Site Remediation

1. Focus on Product Purity and Stability

• High Purity (Typically ≥99%): This is crucial for sodium persulfate to generate sufficient sulfate radicals and achieve efficient oxidative degradation. Excessive impurities (e.g., iron, heavy metal ions) can consume the oxidizing agent, reduce reaction efficiency, and potentially introduce new environmental risks.

• Stability: Sodium persulfate is prone to moisture absorption and clumping. It is essential to select products with secure packaging and easy storage characteristics, and store them in a dry environment to ensure chemical activity remains stable until use.

2. Evaluate Compatibility with Activation Methods

• Sodium persulfate requires activation to exert its strongest oxidizing capacity. Different site conditions (e.g., pH, temperature, groundwater quality) are suited to different activation methods (e.g., thermal activation, iron activation, alkaline activation).

• When selecting a product, its compatibility with specific activation methods and reaction efficiency under field conditions should be assessed to ensure efficient free radical generation.

3. Verify Product Reactivity and Batch Consistency

• In addition to purity, the active oxygen content of sodium persulfate is a critical performance indicator, directly determining the treatment efficiency of the oxidant.

• Reliable suppliers should provide quality inspection reports (COA) for each batch, ensuring consistency in key indicators such as purity and active oxygen content.

• Before large-scale application, small-scale trials using actual site soil/groundwater samples are recommended to verify the product's reactivity and removal efficiency for target contaminants. Data from these trials should guide product selection and dosage design.

II. Recommended Manufacturer of Efficient Oxidizing Sodium Persulfate

HongJian Chemical as a manufacturer of efficient oxidizing sodium persulfate. has become a reliable partner for petroleum-contaminated site remediation projects, leveraging its multiple advantages.
