“…Several studies have documented significant effects of pH on the wetting of surfaces by oil or on the collection of oil by water-wetted substrates (Dimov et al 2000;Svitova et al 2002;Drummond and Israelachvili 2004;Rajaković-Ognjanović et al 2008;Ibrahim et al 2009). …”

“…Some potential advantages of using a packed bed approach to water decontamination include compactness, neatness, and the fact that the sorbent material does not need to be collected, since it is not ever released (Pasila 2004). Factors that have been found to be especially important with respect to oil collection onto packed beds include surface area, effective pore sizes between and within particles in the bed, the void volume, flow rate, and the hydrophobic or hydrophilic nature of the surface (Lee and Han 1993;Briscoe et al 2000;Dimov et al 2000;Palisa 2004;Varghese and Cleveland 2008).…”

“…Cambiella et al (2006) observed that droplet coalescence and collection were greatly assisted if salt was added to the mixture, helping to coagulate the oil. Dimov et al (2000) found that oil droplets could be deposited even onto a hydrophilic substrate through the squeezing action of a receding meniscus. Varghese and Cleveland (2008) reported more effective oil removal in the case of larger oil drops, with finer kenaf particles, with higher filtration pressure, with lower pH, and with the presence of a cationic surfactant.…”

“…The devices and washing procedures available for evaluating detergency in textiles are numerous [5][6][7][8][9][10][11][12][13]. However, the design of devices for testing washing efficiency on hard surfaces is less developed [14][15][16][17][18].…”

Detersive processes are complex systems involving a great number of variables. To determine the effect of these variables on the washing of hard surfaces and fatty soils is the object of this work. The statistical design of experiments has been used to evaluate the influence of factors such as temperature, soil concentration and surfactant concentration on detergency. The experimental trials have been made in a continuous-flow device where the soiling agent is confined in a column filled with borosilicate glass spheres. Solutions of the commercial surfactant Berol Ó LFG61 (a mixture of alkylpolyglucosides and fatty-alcohol ethoxylates) have been employed as the wash bath. Both the design of experiments and the continuous experimental system used proved to be an effective tool for detecting the key variables in the cleaning process. Expressions were developed to simulate detergency levels as a function of the variables assayed, always inside the experimental domain. In the trials with oleic acid as the soiling agent, it was found that the temperature and soil concentration were the most important variables to take into account, while the surfactant concentration was not a significant variable. When a semi-solid mixture of different fatty acids was employed, all the variables assayed proved significant, with high detergency values being reached by combining temperature and surfactant concentrations. Results clearly show that the effectiveness of the surfactant used is influenced by the type and concentration of the soil and thus the intended application of the product being developed should be taken into account when designing detergent formulas.

“…Such measurements can be accomplished with macroscopic surfaces by means of the flat-plate streaming potential apparatus (26)(27)(28)(29), as well as with microscopic particles by using electrophoretic mobility measurements (2,8,10,11,30,31).…”
