Electrokinetic properties of Cassiterite

Australian Journal of Chemistry, 1953
Simultaneous ?-potential and surface conductivity measurements have been made on three samples of cassiterite (SnO2) in water, in solutions of HCl, alkalis, inorganic salts, and the flotation collector reagent sodium cetyl sulphate. It is probable that the intrinsic surface charge of cassiterite in water is negative and that it is due to surface ...

Electrokinetic properties of human cryopreserved platelets

Transfusion Medicine, 1994
SUMMARY. A method for the cryopreservation of human platelets with glycerol/glucose is described which was a simplified modification of the method of Dayian and Pert (1979). The effect of cryoinjury of the platelet surface membrane was investigated by studying the surface electrokinetic properties of the platelet.

Electrokinetic properties of methylated quartz capillaries

Advances in Colloid and Interface Science, 2002
Electrokinetic (zeta)-potentials of methylated (trimethylchlorosilane) quartz capillaries (5-6 microm in radius) were determined in 10(-4) M KCl solution. Over the course of time, the absolute values of the zeta-potential decrease, as a result of the formation of small bubbles on the rough methylated surface, generated from the flowing, nitrogen gas ...

Electrokinetic and adsorption properties of asphaltenes

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1995
Abstract The electrophoretic mobilities of asphaltenes were measured in an aqueous medium and an attempt was made to measure their electrokinetic properties in non-aqueous solvents. The asphaltenes were crushed to fine particles and suspended in the liquid medium.

Electrokinetic properties of natural fibres

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2005
In recent years, the use of natural fibres as reinforcement in polymer composites has attracted increasing attention for partial or complete replacement of conventional inorganic fibres. Besides their lightweight, plant fibres have the advantage of low cost, prevent tool wear during processing and show damage-tolerant material behaviour.

Rheological and Electrokinetic Properties of Sodium Montmorillonite Suspensions

Journal of Colloid and Interface Science, 2000
Because of their particular electric surface properties and crystal structure, most clay minerals possess a very high ion exchange capacity. Furthermore, the surface charge distribution is anisotropic: while faces of the laminar clay particles have a negative, pH-independent charge, edges may be positive or negative, depending on pH.

Electrokinetic properties of textile fabrics

Coloration Technology, 2005
This paper reports electrokinetic phenomena concerning the properties of textile fabrics crucial for dyeing and finishing processes. These interface phenomena have influence on adsorption of surfactants, optical brighteners, dyes and finishing agents due to interaction forces between fibre surface and solutions. Zeta potential, Isoelectric Point, Point

Kaolinite microflotation and electrokinetic properties

Mining, Metallurgy & Exploration, 2011
The kaolinite presence in bauxite ores increases caustic soda consumption during the digestion step in the Bayer process. Depending on the kaolinite content, the utilization of the ore in the Bayer process may be unfeasible. This investigation addressed the variables involved in kaolinite flotation through microflotation experiments in a Hallimond tube

Electrokinetic properties of polyformaldehyde fibers

Journal of Applied Polymer Science, 1977
AbstractElectrokinetic properties, namely, zeta potential (ζ), surface charge density (σ), and surface conductivity (Ks) of polyformaldehyde fibers [poly(oxymethylene) fibers] have been studied in the presence of direct dyes, with or without surfactants and an electrolyte. The anionic dyes increased the negative zeta potential of fibers.

Variation in properties of the sediment following electrokinetic treatments

Environmental Technology, 2016
Many studies have reported variation in properties of the sediment within electrokinetic treatments (EKTs). However, we aim to reveal the variation in properties of the sediment following EKTs through laboratory experiments. We collected sewage-derived sediment from a littoral region, and passed it through a 2-mm sieve.
