PORE STRUCTURE CONTROL OF PHENOLIC RESIN-BASED SPHERICAL ACTIVATED CARBON BY POLYMER-BLENDS

摘要

Pore structure of phenolic resin-based spherical activated carbon can be controlled by adding PVB and PEG into the novolac-type phenolic resin. The micropore distribution of PHSAC added with PVB and PEG becomes wider range. Mesopores with the range of 3~5nm are created in the PHSAC which has good adsorption properties to creatinine. The influences of PVB and PEG adding amount and molecular weight on the pore structure of PHSAC are needed to further study.
