Development of alumina-based ceramic microspheres as adsorbent for the removal of Zn2+, Ni2+, and Mn2+ ions in a fixed-bed column system

Autor: Tatiana Martinez Moreira, Luis Antonio Genova

Publikováno v: Cerâmica, Vol 70 (2024)

Abstract Heavy metals are among the most harmful pollutants to the environment and human health. They are present in various industrial processes, requiring increasingly efficient treatments for removing their excessive concentration at acceptable le

Influence of starch type on characteristics of porous 3Y-ZrO2 prepared from a direct consolidation casting method

Autor: Liliana Beatriz Garrido, Maria Patricia Albano, Luis Antonio Genova, Kevin Paul Plucknett

Publikováno v: Materials Research, Vol 14, Iss 1, Pp 39-45 (2011)

Starch consolidation casting has been successfully used to produce porous ceramics with complex shapes at a relatively low producing cost. In this work, porous 3Y-ZrO2 ceramics were produced using two types of starch (corn and potato). Concentrated (
