"Surface active agents Detergents Determination of cationic-active matter content Part 1: High-molecular mass cationic-active matter", ISO 2871 2:1990.
The indicative colloidal evaluations presented allowed the formulation of informative structure-surface-active characteristics correlations and mathematical processing with correlation coefficients R2 ≥ 0,58.
Various methods were used to estimate the CMC of the surfactant in the aqueous solution based on different intrinsic characteristics of surface active agents, such as surface tension, interfacial tension, thermal conductivity, and electrical conductivity.
The nature of the surface active hydrogen is probed, hydrogen desorption characteristics are discussed and the possible sources of activity loss are considered.
As the clay minerals have the characteristics of large surface, active chemical property and so on, the clay minerals would contact with the fluid in stratum after the reservoir is opened, and the physical parameters of the reservoir rock are significantly changed, such as the change of wettability, permeability and pore structure (Kang and Luo 2000).
Impedance characteristics for three frequency regions were studied bulk solution-influenced high frequency response, medium frequency parameters representing adsorption of surface active lubricant additives at the electrode interface, and low frequency characteristics related to diffusion and charge transfer processes.
The conventional methods of physical fractionation used in the petroleum industry are based on physico-chemical characteristics and include distillation, extraction with solvents, and adsorption by surface active substances.
Biosurfactants are the surface active compounds produced by micro-organisms.
The novel surface active compound should be further chemically characterized.
