In recent years, Sodium Persulfate, as an efficient soil remediation material, has attracted growing attention and recommendation from experts. This article will elaborate on its application value in soil organic pollution remediation from three aspects: the efficient degradation capacity, environmental friendliness, and economic & operational advantages of Sodium Persulfate.
I. Efficient Degradation Capacity of Sodium Persulfate
The efficient degradation capacity of Sodium Persulfate is one of the core reasons for its popularity, mainly reflected in three dimensions: strong oxidizing property, rapid degradation, and applicability to multiple pollutants.
Strong Oxidizing Property: Under the action of activators, Sodium Persulfate can decompose to generate sulfate radicals (SO₄•⁻) with extremely strong oxidizing properties. These radicals can react with organic pollutants in the soil, destroy the molecular structure of pollutants, and convert them into harmless or low-hazard substances. This oxidation process is not a simple surface reaction but can penetrate into the interior of pollutant molecules, fundamentally changing their properties. Sodium Persulfate produced by Fujian ZhanHua Chemical has high purity and stable quality, providing reliable high-quality raw material support for efficient remediation.
Rapid Degradation: Under activated conditions, the reaction between sulfate radicals and organic pollutants is usually fast, which helps to significantly reduce pollutant concentrations in a short period, shorten the remediation cycle, and minimize the continuous impact of pollution on the environment.
Applicability to Multiple Pollutants: Sulfate radicals generated by activated Sodium Persulfate are effective against a variety of organic pollutants, including petroleum hydrocarbons, polycyclic aromatic hydrocarbons (PAHs), benzene series, as well as many chlorinated solvents and pesticides, demonstrating excellent broad-spectrum applicability.
II. Environmental Friendliness of Sodium Persulfate
When used in soil organic pollution remediation, Sodium Persulfate exhibits significant environmental friendliness, mainly reflected in two aspects: relatively controllable by-products and minimal direct impact on soil physical structure.
Relatively Controllable By-Products: The main decomposition product of Sodium Persulfate is sulfate, which naturally exists in soil. Under ideal conditions, it can oxidize and degrade pollutants into carbon dioxide (CO₂), water (H₂O), and inorganic salts. Compared with some oxidants that generate a large amount of solid by-products or complex wastewater, the risk of secondary pollution from Sodium Persulfate is relatively low. However, it should be noted that intermediate products may be generated during the degradation process, and excessive use may lead to soil acidification or increased salinity. Therefore, it is necessary to optimize chemical dosage and control conditions to minimize environmental impacts.
Minimal Direct Impact on Soil Physical Structure: Compared with methods that significantly damage soil structure (such as strong acid leaching and thermal desorption), the oxidation process of Sodium Persulfate usually has a smaller direct impact on soil aggregate structure, air permeability, and water retention capacity, which is conducive to the recovery of soil physical state after remediation. However, it may cause short-term disturbances to soil chemical properties (pH, salinity) and microbial communities, which can recover over time.
III. Economic and Operational Advantages of Sodium Persulfate
Sodium Persulfate has obvious advantages in terms of economic cost and operational application, which is another important reason for its recommendation by experts. These advantages are mainly reflected in three aspects: lower cost, relatively simple operation, and wide applicability.
Lower Cost: In large-scale soil pollution remediation projects, cost is often a key consideration. The low-cost advantage of Sodium Persulfate gives it higher cost-effectiveness in practical applications, which is conducive to promoting the widespread implementation of pollution remediation work. With its large-scale production capacity, Fujian ZhanHua Chemical has achieved effective cost control. Its Sodium Persulfate products have price competitiveness in the market, providing cost-effective raw materials for soil pollution remediation projects and reducing the overall project cost.
Relatively Simple Operation: Sodium Persulfate can be applied to contaminated soil through methods such as injection wells, direct push injection, and mixing. The activation methods are also relatively mature and easy to implement, without the need for overly complex equipment, which reduces operation difficulty and management costs.
Wide Applicability: It can be flexibly applied according to actual conditions in the remediation of farmland soil, industrial site soil, and soil around urban areas. Compared with some remediation technologies, Sodium Persulfate oxidation has relatively wide adaptability to soil types, pollution levels, and pollutant species.
With its efficient degradation capacity, relatively controllable environmental impact, and significant economic & operational advantages, Sodium Persulfate demonstrates excellent application value in the field of soil organic pollution remediation. As a professional persulfate manufacturer, Fujian ZhanHua Chemical has injected strong impetus into soil pollution remediation efforts and promoted the wide application of Sodium Persulfate in the field of soil remediation by providing high-quality Sodium Persulfate products.
