Description

General description

Potassium iodide (KI) is an inorganic potassium salt. Alumina loaded with potassium iodide has been employed as catalyst for the transesterification of soybean oil with methanol. Influence of KI on the in vitro generation of polymorphonudear leukocyte (PMN)-derived oxygen intermediates has been investigated.[1]

Application

Potassium iodide (KI) was used in the preparation of standard iodide stock solution for the determination of iodide by size exclusion chromatography.[2] It may be used in the spectrophotometric determination of advanced oxidation protein products (AOPP).[3]

Effects of potassium iodide, colchicine and dapsone on the generation of polymorphonuclear leukocyte-derived oxygen intermediates.

Y Miyachi et al.

The British journal of dermatology, 107(2), 209-214 (1982-08-01)

The effects of potassium iodide, colchicine and dapsone on the in vitro generation of polymorphonuclear leukocyte (PMN)-derived oxygen intermediates were investigated. These three drugs have beneficial effects on those conditions in which PMNs play an important pathogenetic role. Three oxygen

Determination of iodide in seawater and urine by size exclusion chromatography with iodine-starch complex.

H B Li et al.

Journal of chromatography. A, 918(2), 335-339 (2001-06-16)

A novel method for the determination of iodide by size exclusion chromatography was established. The method was simple and highly sensitive with good precision. Iodide was converted to iodine, then sequestered with starch, and separated from the matrix using a
