Sepiolite

Heavy metals such as cadmium, chromium and manganese are toxic priority pollutants that commonly interfere with the beneficial use of wastewater for irrigation and industrial applications. The sorption of cadmium, chromium and manganese from aqueous solutions onto natural sepiolite has been studied.

Adsorption of Reactive Blue 21 (RB21) onto fly ash (FA) and sepiolite from aqueous solutions was investigated. Batch adsorption experiments were carried out to evaluate the influences of experimental parameters such as initial dye concentration (100–750 mg/l), pH (2–8), adsorbent dosage (1–4 g/l) an

We investigated the electrokinetic properties of sepiolite suspensions using the microelectrophoresis technique as a function of pH in the presence of various electrolytes such as, LiCl, NaCl, KCl, Cu(NO3)2, CaCl2, Pb(NO3)2, AlCl3 and Fe(NO3)3 and then, the adsorption of Cu(II) ion onto sepiolite fr

Surface modification of clays has become increasingly important due to the practical applications of clays such as fillers and adsorbents. The surface modification of sepiolite with [3-(2-aminoethylamino)propyl]trimethoxysilane has been employed. The modified sepiolite surface was investigated by FT

In this study, the removal of nitrite from aqueous solution by adsorption was investigated. Sepiolite and powdered activated carbon (PAC) were used as adsorbents. In order to investigate the adsorption mechanisms, three simplified kinetic models, i.e., pseudo-first-order, pseudo-second-order and int

The effects of treatment and conditioning on sepiolite for the removal of Co2+ and Ni2+ from aqueous solutions were investigated by using a batch-type method. Effects of factors such as pH, concentration, stirring time, stirring speed and sorbent amount on adsorption were investigated. The initial a
