Abstract
Plasma polymerized allylamine films were deposited onto quartz particles for the removal of humic acid, a common water contaminant. Allylamine flow rates of 6.6 and 11.5 standard cubic centrimetres per minute (sccm) were used and the mass of particles varied from 50 to 500 g. At an allylamine flow rate of 6.6 sccm, the atomic concentration of carbon and nitrogen decreased with increasing mass of particles. The isoelectric point and number of positively charged amine groups increased as the allylamine flow rate was increased and/or the mass of particles coated was decreased. Greater humic acid removal was achieved by increasing the allylamine flow rate and/or decreasing the mass of particles coated, which will have important implications for its use in water. © 2014 John Wiley and Sons Inc.
