Under these conditions the adsorbent dose was ≈ 20g.l-1, the equilibrium between the adsorbate in the solution and the adsorbent surface was practically achieved in 90min at pH 1.0. Adsorption kinetics was found to follow a pseudo-second-order rate expression and equilibrium adsorption data of bromothymol blue

01.01.2018· The amount of montmorillonite in bentonite, which is positively correlated with the degree of the useful characteristics of bentonite, can be determined using the methylene blue () test. The test measures the maximum amount of cation that can be adsorbed onto the surface of montmorillonite in the bentonite. When cations are adsorbed onto the montmorillonite surface,

Although the methylene-blue titration has given fast results, it has not demonstrated confidence, due to the semi-quantitative nature of this technique. Generally, the values of CEC decreased from 68 meq/100g to 42

We studied the adsorption of acid blue 129 ions on Mg-bentonite clay from aqueous solution at different temperatures (Fig. 2). The results make it clear that the adsorption on Mg-bentonite clay increases with time. Furthermore, the dye uptake by activated Mg-Bentonite clay was rapid initially up to 25 minutes, followed by a continued rise up to 40 minutes, and 5.397×10-6 mol g-1 of AB129 was
