“…In the titration operation mode (also referred to as a batch method), a feed solution of surfactant is introduced in a number of successive steps into the microcalorimetric cell, where the solid material is maintained in suspension by effective agitation [9,16,18,[24][25][26][27][28]. The size of the titration vessel varies from 2 to 100 mL, depending on the calorimeter design.…”

“…The problem of finding a compromise between sufficient mixing and minimum mechanical heat evolution was recently solved by employing a magnet-driven propeller with a rapid-slow reciprocating motion [9,16,[24][25][26] or a circular horizontal disk moving up and down at low frequency [27]. Titration calorimetry allows a number of successive heat determinations in a single experiment using the same solid sample.…”

[19][20][21][22][23][24][25][26][27][28][29] In this project, authors have chosen easily available, environmental friendly, techno-economic and widely abundant ordinary sand and bagasse obtained from river and local sugar industry, as an adsorbent, respectively. River sand is first and foremost composed of feldspar ( Sugarcane bagasse contains silica and carbon 9.78% and 90.22%, respectively.…”

Techno-economic, sustainable and eco-friendly approaches for removal of the residual surfactants from laundry wastewater (LW) had always been a prime necessity of environment especially for floral diversity. In the present study, river sand and bagasse were used as adsorbents for removal of residual surfactant from LW via adsorption. Anionic content of surfactant of LW (treated and untreated) was determined by hyamine solution. The effect of adsorbent size, mass of adsorbent and duration of adsorption on removal efficiency was studied. Results revealed that 90 micrometer (µm) particle size, 9 grams (g) adsorbent mass and 6 minutes duration for adsorption by sand as an adsorbent reflected 97.6% removal efficiency for surfactants from LW. On the other hand, 150 µm particle size showed 99.2% removal efficiency at 0.1 g adsorbent mass for 2 minutes duration of adsorption using bagasse as an adsorbent. The cementing aspects of treated LW were also investigated and it was found that treated LW by both adsorbents was superior in all the studied properties of cementing parameters. On comparison, bagasse was much better adsorbent with respect to quantity (mass of adsorbent) as well as duration of adsorption to remove residual surfactant from LW.

“…Its crystal structure is then formed by the association of one octahedral layer (O) and one tetrahedral layer (T). Interactions between anionic surfactant and kaolinite have been studied in the past [13][14][15]. In particular, detailed analysis of the features of surfactant adsorption isotherms (shape and position) was performed to derive information about interaction mechanisms [16].…”

Interactions between kaolinite (KGa-2) and a typical anionic surfactant bis(2-ethylhexyl) sulfosuccinate sodium (AOT) have been study to obtain a better knowledge of this system. Firstly, adsorption isotherms of AOT on kaolinite are realized as a function of pH. Stability experiments have been performed between the surfactant and the clay mineral and the bed sediments structure have been studied with Small Angle X-ray Scattering (SAXS). In acidic media, the shape of the adsorption isotherm leads to the following suggestions: firstly, for surfactant concentration below the CMC a surfactant monolayer is adsorbed on the positively charged edge surfaces, and then, for surfactant concentrations above the CMC, a bilayer is adsorbed on the edge surfaces. Consequently, in the first case, the surface becomes hydrophobic and in the second case, the surface becomes hydrophilic and this assumption is verified with hydrophobicity tests. Under alkaline conditions no surfactant is adsorbed on surfaces confirming the adsorption on the edge surfaces in acidic conditions. In agreement, with previous studies [1,2] significant stabilization of kaolinite suspensions can be observed in the presence of high surfactant concentration, in both pH conditions. Finally, structural studies by SAXS provide data about the organization of particles in the bed sedimentation.
