In the course of human production and daily activities, various persistent organic compounds (POCs) enter the soil environment through multiple pathways. These substances are difficult to degrade naturally, and their long-term accumulation will damage soil structure, impair soil fertility, and further pose potential threats to ecological environments and human health. As a high-efficiency soil remediation material, sodium persulfate has demonstrated a significant effect in decomposing persistent organic compounds in soil.

Persistent Organic Compounds: Accumulation Hazards and Degradation Challenges in Soil
Persistent organic compounds in the soil environment are characterized by strong stability and long persistence. After entering the soil, they form complex binding states with soil particles and organic matter, making them difficult to be decomposed and utilized by microorganisms in the natural environment. Long-term accumulation not only deteriorates the physical and chemical properties of soil and reduces its water and fertilizer retention capacity, but also may spread through crop absorption, groundwater infiltration and other pathways, leading to cross-medium pollution.
The molecular structure of persistent organic compounds is highly stable. Factors such as light, heat and water under natural conditions cannot easily destroy their molecular skeletons. Conventional biodegradation methods also have limited effects due to the extremely low utilization rate of these compounds by microorganisms. Therefore, finding efficient and safe artificial intervention methods to achieve rapid decomposition of persistent organic compounds in soil has become an important research topic in the field of soil environmental remediation.
Core Mechanism of Sodium Persulfate for Decomposing Persistent Organic Compounds
Under suitable activation conditions (e.g., heat, alkali, transition metals), sodium persulfate can generate highly oxidizing substances such as sulfate radicals. These active substances can efficiently destroy the stable chemical bonds in organic compound molecules, gradually cracking macromolecular organics into small-molecule, low-toxicity or non-toxic substances, thus realizing the degradation of pollutants.
Different from other degradation methods, the active substances generated by sodium persulfate have a wide reaction range, which can react with various types of persistent organic compounds in soil and adapt to the remediation needs of different pollution scenarios. Its reaction process does not rely on complex microbial systems. Under appropriate conditions, it can initiate high-efficiency degradation reactions in a relatively short time, effectively improving the decomposition efficiency of pollutants. Meanwhile, under reasonable dosage and controllable conditions, sodium persulfate has a low risk of secondary pollution, which meets the eco-friendly requirements of soil remediation and balances remediation effects with soil ecological protection. As a professional manufacturer of sodium persulfate, Fujian Zhanhua Chemical produces sodium persulfate with high purity, up-to-standard active oxygen content and excellent strong oxidizing properties, which can give full play to the above degradation mechanism and help rapidly decompose persistent organic compounds in soil.
Application Advantages of Sodium Persulfate in Soil Remediation
In practical applications for degrading persistent organic compounds in soil, sodium persulfate exhibits significant application advantages. First, fast decomposition rate: it can quickly respond to soil pollution remediation needs and greatly shorten the remediation cycle. Compared with traditional remediation methods, it can significantly improve the efficiency of restoring normal soil functions, enabling the rapid reuse of contaminated soil. Second, wide applicability: it can meet the degradation needs of various persistent organic compounds in different types of soil. Whether it is clay soil or sandy soil, it can exert a stable degradation effect without being excessively restricted by soil type, pollution degree and other factors, showing strong practical adaptability. Third, simple and controllable application process: it does not require complex equipment support, is easy to operate and promote in practical applications, and its application method can be flexibly adjusted according to the specific distribution of soil pollution, ensuring the uniformity and stability of remediation effects. In addition, sodium persulfate itself is stable in nature, almost non-hygroscopic, easy to store and transport over long distances at room temperature, which can effectively reduce operation and maintenance costs in practical applications and provide economically feasible technical support for large-scale soil pollution remediation projects. The sodium persulfate products of Fujian Zhanhua Chemical not only have the above application advantages, but also provide a variety of packaging specifications to meet the needs of remediation projects of different scales.
With its unique and high-efficiency mechanism of action, sodium persulfate has irreplaceable advantages in rapidly decomposing persistent organic compounds in soil. As a leading manufacturer in the industry, Fujian Zhanhua Chemical produces persulfate products that can meet the needs of remediation projects of different scales, and its high-standard sodium persulfate provides strong support for soil pollution remediation. With the continuous development of soil pollution remediation technology, the application of sodium persulfate will become more extensive, injecting sustained impetus into improving soil environmental quality and safeguarding ecological security.
