Calculation of the dynamic sorbent capacity in the presence of two sorbates

Derivatives Based on Cyclodextrin Structure for Adsorption of Heavy Metal Ions and Organic Pollutants in Wastewater

“…The adsorption capacity of the CD‐AA‐AM‐MBA material can be calculated using the following equation: $$$$\begin{equation}\ {Q}_{\mathrm{e}} = \frac{{({C}_0 - {C}_{\mathrm{e}}){\mathrm{V}}}}{{\mathrm{W}}}\ \end{equation}$$$$ $$$$\begin{equation}\ {Q}_{\mathrm{t}} = \frac{{({C}_0 - {C}_{\mathrm{t}}){\mathrm{V}}}}{{\mathrm{W}}}\ \end{equation}$$$$ Q t (mg g −1 ) is the adsorption capacity of the material at time t ; Q e (mg g −1 ) is the adsorption capacity of the material at equilibrium; C o (mg L −1 ) is the initial concentration of copper and lead ion solution; C e (mg L −1 ) is the concentration of copper and lead ion solution at adsorption equilibrium; C t (mg L −1 ) is the concentration of copper and lead ion solution at time t ; V (mL) is the volume of the metal ion solution; W (mg) is the mass of the material.

Mineral Materials Coated with and Consisting of MnOx—Characteristics and Application of Filter Media for Groundwater Treatment: A Review

“…Glauconite can be chemically regenerated and in this form effectively removes metals from water, however, raw glauconite exhibits also exchange capacity. For this reason, glauconite can be used for water purification [58,60,[90][91][92]. Its specific surface area is more extensive in comparison to the previously discussed silica materials (Table 1) and depends on the origin of the rock.…”
