چکیده
In this work, highly hydrophobic carbon sponges with large specific surface area were successfully prepared (denoted as HHCS-1, HHCS-2 and HHCS-3). By simply increasing temperature decreasing heating rate, the sponge showed unique sphere structures at points of each connection. Moreover, structure changes from no obvious fold to fold. HHCS-3 largest 2926.2 m2 g−1 exhibited superior adsorption performance for methanol, acetone toluene, saturated capacity reached high 172, 365 429 mg g−1. The ultralow water vapor absorption rate indicates that HHCSs have excellent hydrophobicity uptakes are only 7.62%, 6.71% 6.25% relative humidity 50%. When was introduced into toluene gas (RH = 50%), toluene-saturated capacities reduced by 7.2−8.6% compared under dry conditions. on is higher than methanol acetone. Kinetic models show onto mainly depends adsorption.

Electrospun Polyurethane/β-Cyclodextrin Composite Membranes for Aerosol Filtration and Adsorption of Volatile Organic Compounds from the Air
Introduction: Electrospun nanomembranes have been used for effective air filtration due to their potential for active surface modification. This study aims to synthesize polyurethane (PU) nanofiber membrane incorporated with different amounts of β-cyclodextrin (β-CD) to capture volatile organic compounds (VOCs) along with aerosol filtration from the air. Material and Methods: First, PU was sy...

23 Since usual processes involve water as absorbent, they appear not always really efficient for the treatment of 24 hydrophobic VOC. Recently, absorption and biodegradation coupling in a two-phase partitioning bioreactor (TPPB) 25 proved to be a promising technology for hydrophobic compound treatment. The choice of the organic phase, the non26 aqueous phase liquid (NAPL) is based on various pa...
متن کاملAdsorption of Volatile Organic Compounds from Aqueous Solution by Granular Activated Carbon (GAC) in Batch System
Chlorinated hydrocarbons and aromatics are the major volatile organic compounds that contaminate the ground water and industrial waste waters. The best way to overcome this problem is to recover the dissolved compounds in water. In order to evaluate the potential ability of granular activated carbon (GAC) for recovery of volatile organic compounds from water, the equilibrium adsorption was inve...
