Origin: Formed within English, by derivation; modelled on a German lexical item. Etymons: peri- prefix, kinetic adj.

Etymology: < peri- prefix + kinetic adj., after German perikinetisch (attributed to G. Wiegner by P. Tuorila 1927, in Kolloidchemische Beihefte 24 12).

Physical Chemistry.

Designating coagulation, aggregation, or flocculation of colloidal particles occurring as a result of Brownian motion.

ΚΠ

1927 Chem. Abstr. 21 2832 Coagulation under Brownian movement is called perikinetic.

1935 Trans. Third Internat. Congr. Soil Sci. I. 39 Owing to perikinetic coagulation, the sedimentation method was a complete failure.

1991 Jrnl. Colloid & Interface Sci. 141 522 An experimental procedure allowing reproducible mixing of colloids and polymers in dilute suspension was used to study perikinetic aggregation resulting from polymer adsorption onto colloids.

1998 J. F. Ranville & R. L. Schmiermund in D. L. Macalady Perspectives in Environmental Chem. ii. 37 Random collisions of small particles due to Brownian motion results in perikinetic flocculation.
