Poly (4-(4-vinylbenzyloxy)-2-hydroxylbenzaldehyde] was evaluated for removing tow concentrations of lead(II) in ppb levels from aqueous media. The effects of the pH condition and the initial lead concentrations on removal were examined. It was found that the metal absorption is best described with the Langmuir model. The R-L values obtained between 0.01 and 0.23 indicate that favorable absorption occurs in the studied concentration ranges. The kinetic study revealed that the metal removal proceeds at a very fast pace-less than 30 s-to reach the maximum capacity. The data fit the description of pseudo-second-order rate. The dynamic column study for real-time practical absorption also was investigated. (C) 2009 Wiley Periodicals, Inc. J Appl Polym Sci 113:2096-2102, 2009
