At the concentrations of ligand commonly used for immobilization (20-200 µg/ml), the expected levels of immobilized ligand would be low in the absence of a mechanism that attract the ligand molecules to the sensor surface. The main mechanism for this concentration process is electrostatic attraction of the ligand to the surface.

The process of electrostatic extrusion as a method for cell immobilization was investigated that could be used for potential applications in medicine. An attempt was made to assess the effects of cell addition and polymer concentration on the overall entrapment procedure, ie, on each stage of immobilization: polymer-cell suspension …

At any salt concentrations, salt ions provide either charge shielding/electrical double layer, 38 often referred to as Debye length 1, 7 or stoichiometric ion binding 8, 9 on the charged protein and column surface. Almost all the chromatography uses some level of salt concentration and hence will have charge shielding effects.

Electrostatic separation enables the separation of a wide range of minerals and this example, separating Pyrite from Silica Sand, provides a good example of the separation process. A feed of …

The experimental results (SI, Table S1) demonstrate that the magnetic COF composite maintained significant chemical stability under neutral to strongly acidic conditions. Even at a pH of 1, the leaching of Fe³⁺ ions into the solution remained minimal, with a maximum recorded concentration of 0.50 ppm.

ERGA ELKRON ESS electrostatic separator provides recovery of the finest metals and mineral particles with size from 0.040 to 8 mm and up to 99.8%. separation and cleaning efficiency of feed material.

Further, secondary separation process was applied to the heavy-mineral concentrate involving magnetic and electrostatic separators. The higher iron content of ilmenite gives it a higher magnetic susceptibility than the rest, allowing it to be magnetically separated from other minerals early in the process.

The froth flotation process was first patented by H. F. K. Pickard, E. L. Sulman and John Ballot in the year 1906. This was nearly 19 years after the first cyanide process patents were filed by MacArthur and the Forests. This process came into light while the scientists were experimenting with the Cattermole process. Table of Contents

The optimum process condition utilized for the triboelectrostatic concentration of the flotation concentrate was determined from the previous investigation conducted by this author [8].
