Interaction of Aqueous Polyethylene Glycol Solutions with Iodine
An experimental study of the interaction of iodine with the ether linkage of some polyethylene glycols was made. The conditions for producing 1:1 complexes of were determined. Some qualitative observations are presented on the effects of polymer weight, polymer-iodine ratios in solution, and on the behavior of these complexes in analytical reactions.
This paper contrasts normal biochemistry reaction with MUG - Indole quick - examination in the suspicious strain of E. coli. The result shows: the biochemistry reaction of this strain conforms with national stardard in the normal examing times, and this strain is non - typical E. coli, but if citrate utilization time is extended to 144 hours, the result is changed to - + - +. The examination of MUG - Indole are negative at all.
