iod-
(aɪəʊd)
combining form of mod.L. iodum iodine, used (chiefly before a vowel) in forming names of iodine compounds. (Before a cons. usu. iodo-, q.v.) Among these are iodaˈcetic a., in iodacetic acid: see iodoacetic adj. s.v. iodo-; its salts are iodˈacetates; ˈiodamide, iodaˈmmonium, compounds formed by the action of iodine on ammonia, mostly of an explosive character; iodˈargyrite Min. = iodyrite; see quot. 1971; iodarˈsenious a., containing iodine and arsenic; iodˈembolite Min. [embolite], the name now given to iodobromite; iodˈethane, iodˈethyl, ethyl iodide; iodhyˈdrargyrate: see iodo-; iodˈhydrate = hydriodate; iodˈhydric a., = hydriodic; iodˈhydrin, an iodine ether of glycerin; iodˈiodide: see iodo-; iodˈozone (see quot.); iodruˈbidium, iodide of rubidium, RbI.
