“…Rutile is chosen because it allows studying anionic surfactant adsorption on positive rutile at the acidic side of the pH of zero net proton charge (pH<pH pznpc ) and cationic surfactant adsorption on negative rutile at the alkaline side (pH> pH pznpc ). Rutile is not of direct importance for soil systems but at the same ionic strength the adsorption behavior of surfactants on rutile is very similar to that on aluminum oxides and hematite when ∆pH = pH-pH pznpc is considered as parameter that characterizes the charge density [134,[139][140][141].…”

Soils are complex and widely varying mixtures of organic matter and inorganic materials; adsorption of surfactants to soils is therefore related to the soil composition. We first discuss the properties of surfactants, including the critical micelle concentration (CMC) and surfactant adsorption on water/air interfaces, the latter gives an impression of surfactant adsorption to a hydrophobic surface and illustrates the importance of the CMC for the adsorption process. Then attention is paid to the most important types of soil particles: humic and fulvic acids, silica, metal oxides and layered aluminosilicates. Information is provided on their structure, surface properties and primary (proton) charge characteristics, which are all important for surfactant binding. Subsequently, the adsorption of different types of surfactants on these individual soil components is discussed in detail, based on mainly experimental results and considering the specific (chemical) and electrostatic interactions, with hydrophobic attraction as an important component of the specific interactions. Adsorption models that can describe the features semi-quantitatively are briefly discussed. In the last part of the paper some trends of surfactant adsorption on soils are briefly discussed together with some complications that may occur and finally the consequences of surfactant adsorption for soil colloidal stability and permeability are considered. When we seek to understand the fate of surfactants in soil and aqueous environments, the hydrophobicity and charge density of the soil or soil particles, must be considered together with the structure, hydrophobicity and charge of the surfactants, because these factors affect the adsorption. The pH and ionic strength are important parameters with respect to the charge density of the particles. As surfactant adsorption influences soil structure and permeability, insight in surfactant adsorption to soil particles is useful for good soil management.

“…The effects of surfactant concentration, temperature, pH and presence of electrolyte on adsorption were examined. There are some works in literature about the adsorption of surfactants on metal oxides [3,[5][6][7]. However activated carbon materials are the most widely used adsorbents for the removal of surfactants from aqueous solutions by adsorption.…”

“…However, to further improve the grade and recovery of mineral and reduce the amount of collector, the use of sodium dodecyl benzene sulfonate (SDBS), sodium dodecyl sulfate (SDS), tween-80(TW) and Triton X-100 (TX) as synergists [22] for manganese ore has been suggested. The effects of these synergists were investigated in additional flotation tests.…”
