Applicability of the equations of Freundlich and Langmuir to the adsorption of the azo dye procion scarlet on paramorphic colonies of Neurospora crassa.
(1987-12-01)
Experiments on the adsorption of Procion Scarlet MX-G by normal hyphae and by paramorphic colonies of Neurospora crassa were performed at pH 2.5, 4.5 and 6.5 at 30 degrees C. The measured adsorption isotherms were evaluated ...

Adsorption of reactive dye on seawater-neutralised bauxite refinery residue
(2013-02-11)
This investigation has demonstrated the need for thermal treatment of seawater neutralised red mud (SWRM) in order to obtain reasonable adsorption of Reactive Blue dye 19 (RB 19). Thermal treatment results in a greater ...

Kinetic, isothermal, and thermodynamic models to evaluate acid blue 161 dye removal using industrial chitosan powder
(2018-03-01)
Textile dyes are often discarded into the environment. Most of them are toxic and their release leads to severe impacts. This study evaluated the potential of industrial chitosan powder as an adsorbent material capable of ...
Adsorption of Acid Yellow 42 dye on calcined layered double hydroxide: Effect of time, concentration, pH and temperature
(2017-05-01)
The adsorption of textile dyes onto Layered Double Hydroxides (LDH) and their thermally decomposed products is a promising strategy for the treatment of contaminated effluents - combining high removal efficiency with ...
Removal of dyes by lignocellulose adsorbents originating from biodiesel production
(2014)
In this study, use was made of tucumã cake, in natura (TCN) and thermally treated (TCT), as potential alternative adsorbents for the adsorption of cationic and anionic dyes. The effects of the parameters: contact time, ...
