Abstract
The water samples were collected from Linag and Pasu waterfalls, and Top Bok hot
spring, situated in Kelantan, Malaysia The sampling and sample treatment was made
according to EPA protocols. Physicochemical measurements of water samples were
performed on site using YSI® 556 Multi-Probe System. DOM fractions were made with
membrane filtration, and total DOM was trapped on C-18 and XAD-4 columns through
the SPE technique. The metallic elements were determined in water samples using F AAS
and GF AAS. Amberlite XAD-4 Resin was found to have more capacity to enrich total
DOM than the C-18 column and membrane filter. The FT-IR spectra of the retentate
showed bands for -OH, -CH, C=O and C-0-C stretching vibrations for phenolic,
carboxylic and carbohydrate functional groups. The metals determined were Pb (II), Fe
(II), Cu (II), Cd (II) and Zn (II); their concentration varied between samples, and overall
concentrations were within the safe limits set by EPA and WHO for water used in
bathing and tourism activities.
