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 adsorption and catalytic activity. From the treatment of volatile organic compounds (VOCs) to the removal of heavy metal ions, white carbon black based composite materials are promoting the upgrading of environmental protection technologies towards high efficiency and low cost.


Atmospheric governance: the "enhancer" of biological filtration
In the process of treating VOCs by biological filtration, the low mass transfer efficiency of hydrophobic organic compounds (such as pentane) is the key bottleneck restricting the removal rate. By adding hydrophobic gas-phase white carbon black to the biofilter, the removal efficiency of pentane can be increased from 60% to 90%. The mechanism is that the methyl groups on the surface of white carbon black form van der Waals forces with organic matter, promoting microbial degradation.


Water treatment: the 'nano catcher' for heavy metals
The adsorption capacity of traditional activated carbon for heavy metal ions such as lead and cadmium is limited (<50mg/g). A magnetically separable heavy metal adsorbent has been developed by combining amino functionalized white carbon black with magnetic Fe ∝ O ₄ nanoparticles. 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.


Soil remediation: a 'degradation accelerator' for organic pollutants
In the remediation of oil contaminated soil, white carbon black based photocatalysts (such as TiO ₂/SiO ₂ composite materials) can increase the total petroleum hydrocarbon (TPH) degradation rate from 30% to 85% within 60 days by generating hydroxyl radicals. More importantly, the material can be reused more than 5 times, reducing repair costs by 60%.
