Solubility

Solution, Solubility, and Solubility Equilibrium
A solution is a homogeneous mixture composed of a solvent, the major component, and a solute, the minor component. The physical state of a solution—solid, liquid, or gas—is typically the same as that of the solvent. Solute concentrations are often described with qualitative terms such as dilute (of relatively low concentration) and concentrated (of relatively high concentration).
In a solution, the solute particles (molecules, atoms, and/or ions)...
Colloids03:22

Colloids

Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles that are visible to the naked eye or can be seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. On the other hand, a solution is a homogeneous mixture in which no settling occurs and in which the dissolved...
Coagulation01:06

Coagulation

Colloidal solids are solid particles suspended in solution. They are usually negatively charged, attracting a compact primary layer of positively charged ions, which attract more counterions to form an electrical double layer. Electrostatic repulsion between the charged double layers prevents the particles from colliding, stabilizing the colloids. These solids are often undesirable because they can contain toxins that are difficult to remove. Coagulation is a technique that helps aggregate and...

Summary

Nanofluids significantly enhance oily soil removal by forming ordered nanoparticle structures in wedge films, reducing cleaning time compared to alkaline solutions. This novel detergency mechanism relies on structural disjoining pressure for effective oil detachment.

Area of Science:

  • Colloid and Surface Science
  • Nanotechnology
  • Materials Science

Background:

  • Oily soil removal is crucial in industrial cleaning processes.
  • Conventional alkaline solutions have limitations in efficiency and environmental impact.
  • Nanofluids offer potential for improved detergency due to unique particle properties.

Purpose of the Study:

  • To investigate the application of nanoparticle structuring in wedge films for oily soil removal.
  • To compare the cleaning performance of nanofluids with conventional alkaline solutions.
  • To elucidate the underlying mechanism of nanofluid-based detergency.

Main Methods:

  • Experimental cleaning of canola oil from glass substrates using five commercial nanofluids.
  • Determination of effective nanoparticle diameter and volume using capillary force balance and microinterferometry.
  • Theoretical analysis using statistical mechanics and Laplace equation-based drop profile analysis.

Main Results:

  • Nanofluids demonstrated significantly shorter oil removal times than alkaline solutions at equivalent pH.
  • Nanoparticle contributions include reduced contact angle, interfacial tension, and increased osmotic pressure.
  • Calculated structural disjoining pressure correlated well with experimental oil cleaning performance.
  • Theoretical analysis confirmed nanofluid spreading, wetting, and oil detachment mechanisms.

Conclusions:

  • Nanofluids provide a novel and effective mechanism for oily soil removal.
  • The enhanced detergency is attributed to the formation of ordered nanoparticle structures and the resulting structural disjoining pressure.
  • This study validates a new approach to detergency leveraging nanoparticle behavior in confined spaces.
