This paper presents the synthesis of mesoporous aluminosilicates from a hybrid organic-inorganic xerogel, using the chitosan biopolymer together with a hydrothermal treatment process as structural modeling tools. The ...

Low-cost adsorbents constituted by Fe-modified-aluminosilicates (laminar and zeolite type minerals) were developed and characterized to be used in the arsenic removal from groundwater. Iron activation was carried out “in ...

This work concerns to the development and characterisation of support, active layer and tubular composite membranes (CM) from natural aluminosilicates as principal components (clay, bentonite, feldspar, quartz, alumina). ...

This work reports the preparation of two series of Ni-aluminosilicates by the sol–gel and the co-precipitation methods. The main difference between the two processes of synthesis is the pH of the initial mixture, 2 for the ...
