ABSTRACTThis research work focuses on combining ball milling and ultrasonication to produce nano-size clay particles. Our work also emphasizes on increasing the specific surface area of montmorillonite clay particles by reducing the particle size to nanometer dimensions. We have characterized the as-received clay particles by using particle size analysis based on laser diffraction and found that the size of the clay particles is not consistent and the particle size distribution is very broad. However, after the unique treatment and processing, the clay particles were obtained in nanometer dimensions with narrowed particle size distribution.

Abstract. We tested laser diffraction particle size analysis in poorly coherent carbonate platform cataclastic breccias and unfaulted quartz-rich eolian sands, representing low- and high-strength granular materials, respectively. We used two different instruments with different sample dispersion and pumping systems and several wet and dry analytical procedures that included different pump speeds, measure precision tests with and without sample ultrasonication, and different dispersant liquids. Results of our work indicate that high strength material is not strongly affected by analytical operating procedures, whereas low strength material is very sensitive to the pump speed, ultrasonication intensity, and measurement run time. To reduce such a data variability, we propose a workflow for analytical tests preliminary to the set up of the most appropriate SOP.

AbstractModem disc centrifuge technology has extended the range of application of sedimentation particle size analysis to include the submicron region. An overall size range of approximately 10 nm to 100 pm is now accessible. The principles of both the disc centrifuge photosedimentometer, which employs optical detection with full Mie light scattering corrections, and the X-ray disc centrifuge are described. Examples of their application to a variety of samples are given to illustrate the performance characteristics of the instruments including a direct comparison of resolving power with that of the laser diffraction technique.

Most colloidal samples have a non-negligible imaginary component of the effective refractive index due to scattering and absorption losses. In this paper we analyze the requirements on a differential refractometer so that it can be used to measure the real part of the effective refractive index increment in colloids for particle size analysis.
