“…They studied stability, adsorption, and electric properties of the carboxymethylcellulose/γ-Al 2 O 3 system using different techniques such as electric polarizability, mobility, and relaxation time, pointing out that the colloid stability is driven by the effective charge of cmc-alumina particles which is determined by different factors (surface charge, number of dissociated carboxylic groups of cmc chains, and the condensed counterions) [18]. However, there are only few investigations on the influence of surfactants on the polymer adsorption on the mineral oxide surfaces [19,20]. In such case, the addition of surfactants to the polymer/ oxide suspensions can change their properties even to a greater extent.…”

The aim of this study was to investigate the influence of different types of surfactants on the adsorption, stability, and electrokinetic properties of the carboxymethylcellulose/alumina system as well as the interactions between the surfactants and the polymer. The authors decided to use fluorinated and silicone surfactants besides the conventional hydrocarbon ones. The obtained results showed that carboxymethylcellulose (cmc) adsorption increased in the presence of surfactants due to the formation of polymer-surfactant complexes (the increase of the adsorption from about 0.020 mg m −2 for pure cmc to 0.030 mg m −2 for MTAB/cmc and SJ2/cmc mixtures). The obtained complexes of 0.00336% MTAB/cmc and 0.004% S-106a/cmc reduced the surface tension of water more efficiently than pure surfactants of the same concentration (from 70.06 to 62.39 mN/m and 71.06 to 64.26 mN/m respectively). Stability of the alumina suspension was studied as well. The obtained results indicate that the addition of carboxymethylcellulose, surfactants, and the cmc-surfactant complexes leads to the increase of alumina suspension stability. The mechanism responsible for stabilization was electrosteric one. The largest stability was observed for the systems containing the mixture of cmc and surfactants. The reason for this is the formation of the adsorption layer composed of alternately arranged regions of polymer and surfactant complexes. Electrokinetic measurements of the studied systems allowed to describe the structure of the electrical double layer and to determine the point of zero charge of alumina (pHpzc ≈ 7.5). The addition of the polymer as well as surfactants leads to the charge reversal of alumina.

“…A lot of studies have been carried out on the adsorption behavior of polymers between minerals such as starch and quartz, talc, hematite, chalcopyrite, manganese dioxide, and colloidal chromium(III) oxide . Various effects, such as those on the particle size, background ions, and temperature, were investigated in those studies .…”

A hydrophobic polyacrylamide (HPAM) was synthesized by aqueous free-radical chain polymerization to understand the adsorption action of the polymer on the calcite during operating stimulation. The polymer was designed as acrylamide (AM)/2-acrylamide-2-methylpropanesulfonic acid (AMPS)/2-methacryloyloxyethyl 12-alkyl dimethyl ammonium bromide (MADA). The structure of the polymer was characterized by Fourier transform infrared spectroscopy. The adsorption properties of the polyacrylamide onto pure calcite was investigated. When we compared the f potentials of the calcite particles in the presence and absence of HPAM, the adsorbed amount was affected by different factors, and the adsorption behaviors were examined to determine the adsorption layer. The results of the f potential measurements indicated that the particles were negatively charged between pHs of 6 and 12, and the presence of HPAM did not reverse that. Equilibrium adsorption studies showed that the adsorbed amount was affected by the concentration of HPAM, liquid-to-solid ratio, calcite particle size, concentration of background ions, and temperature, which were related the adsorption behaviors of HPAM. Hydrogen bonds between HPAM and calcite were important because the adsorbed amount was significantly reduced when the hydrogen bonds were broken by urea. It is necessary to develop a more active reagent that can break the hydrogen bonds and improve the effect of hydraulic fracturing.

“…This observation might be confirmed by the obtained data of the adsorption layer thickness (Table 4). It is also known that the structure of the created complexes is as follows: GG-surfactant-GG-surfactant which means that polysaccharide is directly bonded to the surface of the solid and surfactants molecules are present in the upper parts of the electrical double layer (Grządka 2013). Such a conclusion might be drawn on the basis of the elektrokinetic results (Table 3).…”

“…The adsorption of polysaccharide in the presence of surfactants increases (Table 4) which is the effect of complex formation between these two adsorbates. The nature of these complexes depends on the chemical character of both the polymer and the surfactants and was discussed in my earlier papers (Grządka and Chibowski 2012;Grządka 2013). What is more, the created adsorption layer in the presence of surfactants is more expanded towards the liquid phase than in the case of the system containing only 100 ppm GG.…”

Stability of the manganese dioxide (MnO 2 ) suspensions by non-ionic guar gum (GG) in the absence or presence of the surfactants: anionic sodium dodecyl sulphate (SDS), cationic hexadecyltrimethylammonium bromide (CTAB) and non-ionic Triton X-100 (t-octylphenoxypolyethoxyethanol) and their equimolar mixtures (SDS/TX-100; CTAB/TX-100) was measured using turbidity. The obtained results of the manganese dioxide suspensions stability were discussed together with the adsorption data and with the data concerning the thicknesses of the adsorption layers. In order to gain more information about the structure of the electric double layer surface charge density and the zeta potential measurements were performed. The obtained results show that the addition of guar gum to the MnO 2 suspensions increases MnO 2 stability. The larger this increase is, the higher is the concentration of the polymer (concentration range 10-200 ppm). Moreover, the addition of single surfactants also causes the increase in the effectiveness of stabilizing the manganese dioxide suspensions. The reason for that is formation of multilayer complexes between the polymer and the surfactants. In such a system both the adsorption of polymer and the thickness of polymer adsorption layer increase. The greatest increase in the stability of MnO 2 /GG suspensions was provided by the mixture of anionic and nonionic surfactants due to a strong synergistic effect. Also, mixing the polymer and two surfactants reduces the stability of the suspension.
