The addition of a quaternary group in biopolymeric material increases the adsorptive capacity of Acid Blue 25 textile dye
(2019-08-01)
The quaternization of chitosan molecules creates materials with high adsorptive capacity towards textile dyes, which renders them capable of rapidly removing such dyes from a solution. In this study, a novel material was ...
Melamine adsorption on carbon materials: impact of carbon texture and surface chemistry
(Royal Society of Chemistry, 2020-04)
In this work, a comparative study between three carbon materials has been carried out to investigate the impact of the micro/mesoporous structure of the carbon substrate on their adsorption capabilities. The study included ...
Influence of pyrolytic temperature on uranium adsorption capability by biochar derived from macauba coconut residue
(Associa????o Brasileira de Energia Nuclear, 2018)
Effect of nickel loading on hydrogen adsorption capacity of different mesoporous supports
(Springer, 2019-10-03)
Pure siliceous and aluminosilicate mesoporous molecular sieves of MCM-41 type have been used as support for nickel incorporation (2.5 wt%) by wet impregnation method. The hydrogen adsorption capacities at 77 K of these ...
The corn influence on the adsorption levels of aflatoxin B1 and zearalenone by yeast cell wall
(Wiley, 2013-01)
Aims: To in vitro evaluate the influence of the corn on the adsorption levels of aflatoxin B1 (AFB1) and zearalenone (ZEA) by yeast cell walls (YCWs). Methods and Results: Two commercial YCWs were studied. The YCWs contain ...
