“…A P(V) fractionation protocol of the loaded samples confirmed that the phosphate-sorption process involves the formation of calcium phosphate mineral forms. Saffaj et al (2004) used low-cost ZnA1 2 O 4 -TiO 2 ultrafiltration membranes for removing Cd(II) and Cr(III) ions from water. The membrane presents interesting retention properties with regard to the heavy metal ions and dyes.…”

Application of polymeric membranes for the adsorption of hazardous pollutants may lead to the development of next-generation reusable and portable water purification appliances. Membranes for membrane adsorption (MA) have the dual function of membrane filtration and adsorption to be very effective to remove trace amounts of pollutants such as cationic heavy metals, anionic phosphates and nitrates. In this review article, recent progresses in the development of MA membranes are surveyed. In addition, recent progresses in the development of advanced adsorbents such as nanoparticles are summarized, since they are potentially useful as fillers in the host membrane to enhance its performance. The future directions of R&D in this field are also shown in the conclusion section.

“…Most of which have disadvantages of operating in a successive steps of heterogeneous reactions, or distribution of substances between different phases that usually require a lengthy operating period and a large area [4,5]. Membrane processes are of great interest because they reduce the number of unit operations, recycle process water, and recover valuable products for other applications [5]. Additional inherent advantages, such as selective separation, continuous and automatic operation, relatively low capital/ operating cost, easy scale-up and low space requirement, made membrane filtration an attractive alternative compared to conventional treatment [6][7][8][9].…”
