| 11 | The removal of arsenic from (ground)-water by adsorbent loaded in polymeric microspheres显示文摘Arsenic is a natural tasteless and odourless element,existing in the earth's crust at average levels of between two and five thousands micrograms per liter (parts per million) . Arsenic is highly toxic to humans, who are exposed to it primarily from air,food and water. The occurrence of arsenic in groundwater is due to geological composition of soil. High concentrations of arsenic in water are the result of dissolution or desorption of ferric oxides and the oxidation of mineral arsenopyrites. Arsenic in drinking water has an important impact on the human health,especially in the less developed countries. Different methods exist to remove arsenic from aquatic media,and one of them is by adsorption. In this work,the adsorption of both As(III) and As(V) by means of novel microspheres has been investigated. In particular,TiO2 has been embedded into polymeric microspheres PES (PolyEtherSulphone) and PEEK-WC (PolyEtherEther-Ketone) . The main advantages of this encapsulation adsorption material are: no loss of adsorbents into the water stream,easy to be used and scaled-up. | FIGOLI A HOINKIS J CRISCUOLI A FRANZ C DE RYCKE M BLOCK C DEOWAN S A ISLAM R DRIOLI E | 2012 | Journal of Harbin Institute of Technology(New Series)2012，19，1： | 0 |
