The principle is electrostatic forces of attraction. Greater the valency of flocculationg ion, greater is the coagulation power. T1 - Rediscovering the schulze-hardy rule in competitive adsorption to an air-water interface. AU - Stenger, Patrick C. AU - Isbell, Stephen G. AU - Hillaire, Debra St. AU - Zasadzinski, Joseph A. PY - 2009/9/1. Y1 - 2009/9/1 Abstract The applicability of the Schulze–Hardy rule to haematite and haematite/humate mixtures has been investigated by measuring the rate of fast and slow coagulation after the addition of increasing concentrations of mono, di and trivalent ions.

After that, hydrophobic colloids can be effectively flocculated by multiply charged ions ( cations or anions) of opposite charge when exposed to electrolytes . The chemical nature of the ions is of secondary importance. Multiply charged ions such as the aluminum The DLVO theory of colloid stability provided an explanation of the long-standing Schulze–Hardy rule, that the critical coagulation concentration (c.c.c.) is proportional to some inverse power of the counter-ion valency (). For particular limiting cases the inverse power exponent was calculated to be either 2 or 6 The Schulze-Hardy rule (1) and the low charge DH limit (3) were both derived theoretically. On the other hand, the inverse Schulze-Hardy rule was only given as an empirical dependence based on experimental observa-tions.  Therefore, the aim of this paper is to present the derivation of the inverse Schulze-Hardy rule … This is known as the Schulze-Hardy rule. Derjaguin and Landau and Verwey and Overbeek worked independently and used the knowledge from Schulze-Hardy rule to describe the stability of lyophobic colloids to develop this theory (the classic DLVO theory) which explains the result of particle interaction in lyophobic colloids.

Specifically, it can be shown that the critical coagulation concentration is inversely proportional to the coion valence. Here the derivation of the inverse Schulze The Schulze-Hardy rule (1) and the low charge DH limit (3) were both derived theoretically.

This rule is addressed theoretically and confronted with recent experimental results. The commonly presented derivation of this rule assumes symmetric electrolytes and highly charged particles. Both assumptions are incorrect. Symmetric electrolytes containing multivalent
The inverse Schulze-Hardy rule was recently proposed based on experimental observations. This rule describes an interesting situation of the aggregation of charged colloidal particles in the presence of the multivalent coions.

The results reported here show that the standard Schulze-Hardy-Rule (SHR), based only in the valence z, is not longer valid to obtain the right values of CFC. In this work it is reported a correct determination of CFC for di- and tri-valent ions using different types of silica nanoparticles. The Schulze-Hardy rule states that the critical (salt) concentration required to coagulate an electrostatically stabilized suspension is inverse proportional to the 6th power of the valency of the ions. Does this rule equally apply to peri- and orthokinetic coagulation? Explain why or why not. Schulze Hardy Rule • This rule is valid only for system in which there is no interaction between electrolyte and ion of double layer of particle surface.
