Removal of toxic arsenate from drinking water is a global problem affecting more than one hundred million people worldwide. Arsenate in water causes high rate of diseases even in low dosage. Arsenate should be removed from drinking water to a very low concentration below 10 μg/L according advice from the World Health Organization. Amine modified polyketone can be used as an adsorbant for this purpose. It should be known how high the arsenate uptake capacity to make comparison with other adsorbants and technologies possible. To show functionality as an adsorbant for arsenates, amine modified polyketone was measured in a continuous flow adsorption column. These measurements were used in two different adsorption models to calculate adsorption capacity. Measurement and adsorption models show good agreement, thus adsorption models provide a reliable basis for comparing amine modified polyketone to other adsorption based technologies. Adsorption experiments, and model results show that amine modified polyketone has high arsenate uptake capacity up to 190 mg/g polyketone resin. This value is much larger that uptake capacity for competing technologies such as activated alumina and activated carbon which have capacities ranging from 10 to 50 mg/g. This high uptake capacity by itself makes amine modified an excellent adsorbant. Furthermore amine modified polyketone is shown to capable of regeneration, which makes repeated usage possible.
