Ice-templated geopolymer beads for dye removal
Journal of Colloid and Interface Science, 2020 Geopolymer beads, conceived as alternative low cost adsorbents for wastewater treatment, were shaped by a dripping technique in liquid nitrogen, through an ice-templating process. PEG600 was added as a binder to ease the process, standardizing the beads dimension.

Activated Biochars Used as Adsorbents for Dyes Removal
Chemical Engineering Transactions, 2018 Adsorption represents one of the most interesting technique for the removal of pollutants from wastewaters. Activated carbons show the best performances on this kind of processes but their high production costs limit their applications. In this context a big challenge is to find new materials having characteristic similar to those of commercial ...
