Ligand adsorption of adenine and adenosine on poly(vinyl chloride) bound cobalt(II)–carboxylated diaminoethyl complex

The sorption behavior of a nickel-insolubilized humic acid system in a column arrangement

“…6. Some researchers [13] have focused on the breakthrough curves obtained at the loading step of the SPE in order to obtain the amount of the sorbed analyte, using the following equation,…”

“…In a simple SPE system which consists of a peristaltic pump, column, detector, and fittings, optimization of some parameters such as flow rate and temperature may be difficult. Because of this, usability of the reported calculation method [13] probably fails in simple SPE systems. In fully automated SPE systems, flow rate, temperature, and degassing of solutions are more controllable and more definite.…”

“…Table 2 represents the amount of the Ni (II) stripped by 1 M HCl solution, and with 98 ± 2% breakthrough recovery, the amount of the Ni (II) stripped was evaluated as that sorbed. The amount of the Ni (II) sorbed by INaA was also calculated from the loading curves, using a reported calculation method [13] and given in Table 2.…”

Role of Different Bleaching Earths for Sunflower Oil in a Pilot Plant Bleaching System

“…Scatchard plot for all colour pigments can be seen from Figure 5. When the Scatchard plot exhibits a deviation from linearity, greater emphasis is placed on the analysis of the adsorption data in terms of the Freundlich model, in order to construct the adsorption isotherms of the sorbent at particular concentration(s) in solutions [Gezici et al, 2005;Ozdere et al, 2003]. If the Scatchard plot is linear with a negative slope, it is related to the interaction between the analyte and the binding sites that follows the Langmuir model [Kara et al, 2008].…”

Oxidation of benzaldehyde in films by Oxo-Cr(V) salen derivatives at solid/liquid interface

“…A number of studies on the redox chemistry of chromium(V) and the mechanism of oxygenation of inorganic nitrite [24] and vanadium(IV) [36] by oxochromium(V) salen complex, where salen = N ,Nethylenebis (salicylideneimine) in acetonitrile medium, have recently been reported by us. Determination of the rate control step in ligand-exchange reactions have been carried out recently by Ayar and co-workers [37][38][39][40].…”
