What is the unit for distribution coefficient?

Kd : Distribution coefficient is defined as the ratio of equilibrium concentrations C of a dissolved test substance in a two phase system consisting of a sorbent (soil or sewage sludge) and an aqueous phase; it is a dimensionless value when concentrations in both phases are expressed on a weight/weight base.

What is the use of distribution coefficient?

The use of distribution coefficients (log D) for the analysis of structure-activity relationships of ionizable compounds is described. (D is the ratio of the equilibrium concentration of compound in an organic phase to the total concentration of un-ionized and ionized species in the aqueous phase at a given pH.)

What is a distribution coefficient?

distribution coefficient. [‚dis·trə′byü·shən ‚ko·i′fish·ənt] (optics) One of the tristimulus values of monochromatic radiations having equal power, usually denoted by x, y, z. (physical chemistry) The ratio of the amounts of solute dissolved in two immiscible liquids at equilibrium.

What is the distribution coefficient?

Distribution coefficient is the ratio of the concentration of both ionized and un-ionized species of a compound in a mixture of two immiscible phases . We can denote this phenomenon as “D”.

How do you calculate partition coefficient?

The partition coefficient can be calculated using the following equation: D = C A / C B, where C A is the concentration of an element in phase A and C B is the concentration of an element in phase B. A value of D > 1 indicates that the element is compatible, it is preferentially accepted by the mineral.

What is KD in chemistry?

Kd stands for Dissociate Constant (receptor affinity in pharmacology, chemistry) This definition appears rarely and is found in the following Acronym Finder categories: Science, medicine, engineering, etc.
