The application of silicic acid in water treatment mainly stems from its unique complexing and precipitation ability. It can effectively combine with heavy metal ions and certain harmful anions in water to form insoluble solid precipitates, thus achieving the goal of removing these pollutants. For example, in treating industrial wastewater, silicic acid is often used as a chelating agent to help remove toxic heavy metals such as lead, mercury, and cadmium, preventing them from entering the ecosystem and posing a threat to the environment and human health. In addition, silicic acid can react with phosphate ions in water to reduce the nutrient salt content in water, helping to control eutrophication problems. In analytical chemistry, silicic acid is often used for chromatographic analysis and sample pretreatment. Silica-based solid-phase extraction materials can adsorb and concentrate trace amounts of organic pollutants or inorganic ions, improving the sensitivity and selectivity of detection. At the same time, silica gel chromatography is widely used in the separation and purification of biological macromolecules and polymers, which is of great significance for scientific research and quality control. However, the use of silicic acid may also bring some environmental problems. Excessive accumulation of silicate salts in water may affect water hardness and affect the survival of aquatic organisms. In addition, the solid waste generated during the treatment process if not properly handled may become a secondary pollution source. Therefore, we need to continuously research to explore more environmentally friendly silicate stabilization and disposal technologies, while also establishing a comprehensive monitoring system to monitor the impact of silicate use on the environment in real time. In the constant innovation of water treatment technologies, the application of silicic acid is also gradually optimized and expanded. For example, by adjusting the shape or compounding with other additives, the efficiency of removing specific pollutants such as the complexation ability of certain insoluble metal ions can be improved. In addition, researchers are exploring the combination of silicic acid with advanced nanomaterials such as nano-zero valent iron and activated carbon to achieve high-efficiency, selective adsorption and removal of heavy metal ions and organic pollutants. In the field of environmental remediation, silicic acid also shows potential. It can form stable complexes with heavy metals and certain persistent organic pollutants in soil, reducing their bioavailability and mobility, thereby reducing the potential risks to the environment and living organisms. However, this also requires solving the problems that silicate salts may accumulate in soil, such as affecting the physical and chemical properties of soil and affecting the growth of crops. Faced with these challenges, researchers are conducting in-depth research to develop more efficient and environmentally friendly applications of silicic acid and post-processing strategies. This includes researching new silicate stabilizers, developing resource-efficient technologies for the utilization of silicate waste, and optimizing the application conditions of silicate in water treatment and soil remediation. At the same time, policymakers and managers need to develop corresponding regulations and standards to ensure that the use of silicate can effectively solve environmental pollution problems without introducing new environmental risks. As an important chemical substance, silicate has played an important role in solving real-world problems. However, we should also be aware that the use of any chemical substance should follow sustainable and safe principles. Only in this way can we leverage the power of chemistry to improve our lives while protecting the environment we depend on.
