Environmental Earth Sciences, 79(18), 415.https://repoemc.ukm.my/handle/123456789/1601The water of Langat River is not suitable for drinking without treatment because of chemical pollution from both the point and non-point pollution sources, although it is one of the primary sources of drinking water in Selangor state, Malaysia. There is no significant study in Malaysia that has investigated the efficiency of treatment plants to remove metals from treated water. Therefore, Chelex 100 resin-ion exchanged method was applied to investigate the raw water samples and treated water samples of eight treatment plants.enMalaysiaTrace metalsContaminationIon exchangeDrinking waterJournal
