资源简介：
A filter media having lignite-derived activated carbon， polyacrylic acid (PAA)， a commercially available copper-zinc alloy， and polydiallyldimethylammonium chloride (PolyDADMAC) or Luviquat??， which is Poly[(3-methyl-1-vinylimidazolium chloride)-co-(1-vinylpyrrolidone)]， combined and used as suitable replacement for TOG bituminous coal-based activated carbon， silver， and PolyDADMAC. Functional groups in lignite-based activated carbon interact with the polyacrylic acid. Functional groups such as calcium， iron， or aluminum oxide/hydroxide of lignite-based activated carbon interact with PAA， and help hold the PolyDADMAC in place. The additional presence of a copper-zinc alloy enhances the filter anti-microbiological performance.
