given ionic strength called the critical coagulation concentration, most colloids can be forced to undergo catastrophic instability, which is sometimes called The critical coagulation concentrations, cK, are small (often 1 mmol/L) because the cations are zation is called the critical coagulation concentration,. cK. *Critical Coagulation Concentration: concentration of specific ions required to produce rapid aggregation in a suspension of latex particles. Why UltraClean av S García García · 2007 · Citerat av 60 — The DLVO theory defines the critical coagulation concentration (CCC) value as the electrolyte concentration that balances the attractive and repulsive potential The critical coagulation concentration of salt was predicted to decrease as the pOH of the black liquor was increased. The predictions at 65 °C and moderate the uncoated particles, as the critical coagulation concentrations (CCC) of the in NaNO3 aggregation was not observed up to an electrolyte concentration of According to DLVO calculations, the critical coagulation concentration (CCC) indicated a trend of increasing colloidal stability with increased concentration of Flocculation was apparent at much lower concentrations of FeCl3 and Al-2(SO4)(3) Aluminium sulfate, Critical coagulation concentration, Ferric chloride, Floc Kinetic determination of critical coagulation concentrations for sodium- and calcium-montmorillonite colloids in NaCl and CaCl2 aqueous solutions2007Ingår i: The critical coagulation concentration of salt was predicted to decrease as the of pOH (3.5) and salt concentration (1.9 M) were found to be in good agreement av I Neretnieks · 1978 · Citerat av 7 — gels was made within the KBS project by I+eBel 1978 (4). In this investigation the critical.

Critical coagulation concentration

Here, the concentration of particles is high so that the classic DLVO theory, which is based on the interactions between two particles, can be inapplicable. Abstract: Critical coagulation concentration (CCC) is a key parameter of particle dispersions, since it provides the threshold limit of electrolyte concentrations, above which the dispersions are destabilized due to rapid particle aggregation. A computational method is proposed to predict CCC values using Critical coagulation concentration (CCC) of a biocolloidal suspension is investigated theoretically by taking into account the influences of cationic absorption in particulate membrane phase, variation in dielectric constant, size of charged species and nonuniform distribution of fixed membrane groups. The table below summarizes the critical coagulation concentration (CCC) ranges for different net charge of the counter ion. The charge is expressed in units of elementary charge.

The critical coagulation concentration (CCC) is a concept in wastew ater treatment and clay science that states that for a given colloid in suspension there is a concentration of electrolytes at 2005-12-30 2016-02-01 The ratio of the critical coagulation concentration (CCC) of ical predictions are not uncommon (3, 4), the Schulze– counterions is evaluated for spherical particles and asymmetric Hardy rule is still widely adopted in practice for its conve-electrolytes. A perturbation method is adopted to solve the Pois-nience. 2016-02-01 The ratio of the critical coagulation concentration (CCC) of counterions is evaluated for spherical particles and asymmetric electrolytes. A perturbation method is adopted to solve the Poisson-Boltzmann equation governing the electrical potential distribution of the system under consideration. On th … Abstract: Critical coagulation concentration (CCC) is a key parameter of particle dispersions, since it provides the threshold limit of electrolyte concentrations, above which the dispersions are destabilized due to rapid particle aggregation. A computational method is proposed to predict CCC values using critical coagulation concentration otherwise critical aggregation concentration (rus. критическая концентрация коагуляции otherwise порог коагуляции) — minimum concentration of a coagulant that causes rapid coagulation.

Olivier Grunberger. 2012-09-26 2006-04-13 The ionic concentration where the repulsive energy barrier is completely screened and rapid aggregation occurs is known as the critical coagulation concentration. 2020-03-27 2013-08-14 If the critical coagulation concentration of a mixture of two electrolytes and corresponds to concentrations of the two components of and whereas the c.c.c.'s of and taken separately are and then the effects of the electrolytes are said to be additive if ; they are synergistic if ; and antagonistic if . The aggregation kinetics was determined from the decrease in particle concentration with time at different electrolyte concentrations. The DLVO theory defines the critical coagulation concentration (CCC) value as the electrolyte concentration that balances the attractive and repulsive potential energies between the particles, making aggregation diffusion-controlled. Standard methods for soil grain size analysis are based on the sedimentation velocity of particles, described by Stokes’ law.
