White carbon black is the "pioneer of purification" in the field of environmental protection
Atmospheric governance:
VOCs adsorption: The adsorption capacity of gas-phase white carbon black for toluene reaches 200mg/g, which is three times that of activated carbon. After application in industrial waste gas treatment, the emission concentration is reduced from 200ppm to 10ppm.
Desulfurization and denitrification: The white carbon black catalyst loaded with Fe ₂ O Ⅲ achieves a 95% conversion rate of SO ₂ and an 85% removal rate of NOx at 200 ℃.
Innovation in Water Treatment:
Heavy metal adsorption: Amino modified white carbon black has an adsorption capacity of up to 150mg/g for Pb ² ⁺, and its pH range has been expanded to 2-10.
Organic degradation: TiO ₂/white carbon black composite photocatalyst achieves a 90% degradation rate of methyl orange under visible light, with a reaction rate five times higher than pure TiO ₂.
Soil remediation:
Degradation of polycyclic aromatic hydrocarbons: After loading humic acid onto white carbon black, the degradation half-life of benzo [a] pyrene was shortened from 120 days to 30 days.
Retention improvement: After adding 5% white carbon black to pesticides, the half-life in soil is extended to 45 days, and the utilization rate is increased by 30%.
