White carbon black: a "nano purifier" for environmental governance
Faced with environmental challenges such as air pollution, water pollution, and soil remediation, white carbon black has become an emerging "star material" in the field of environmental protection due to its high specific surface area and strong adsorption. In the process of treating VOCs by biological filtration, hydrophobic gas-phase white carbon black forms van der Waals forces with organic matter through surface methyl groups, which can promote microbial degradation and increase the removal efficiency of pentane from 60% to 90%. For example, Black Cat Corporation utilizes the technology of extracting white carbon black from rice husk ash, which not only reduces raw material costs by 30% and carbon emissions by 40%, but also increases the market share of the product in the field of atmospheric treatment from 5% in 2020 to 25% in 2025 through surface hydrophobic modification.
In the field of water treatment, amino functionalized white carbon black can be combined with magnetic Fe ∝ O ₄ nanoparticles to develop a magnetically separable heavy metal adsorbent. Its adsorption capacity for Pb ² ⁺ can reach 200mg/g, and solid-liquid separation can be completed within 5 minutes. This material has been applied to the treatment of electroplating wastewater, reducing the concentration of heavy metals in the effluent to below 0.1mg/L, meeting the standards for drinking water.
