TL;DR: In this article, the basic hydrolysis product of amoxicillin (AMO), ampicillin (AMP) or carbenicillin (CAR) reacted with potassium iodate to form I2, which further interacted with Br-, resulting in the formation of [I2Br]- anionic complex.
Abstract: In a weak acid medium, the basic hydrolysis product of amoxicillin (AMO), ampicillin (AMP) or carbenicillin (CAR) reacted with potassium iodate to form I2, which further interacted with Br-, resulting in the formation of [I2Br]- anionic complex. Then an ion-association complex [I2Br][ MV] was formed owing to the interaction of [I2Br]- with methyl violet, which led to a significant enhancement of resonance Rayleigh scattering (RRS) and the appearance of a new RRS spectrum with the maximum wavelength at 333 nm. Under certain conditions, the intensity of RRS (ΔI) was directly proportional to the concentration of penicillin antibiotics in the range of 0.08-2.0 μg/mL. The method exhibited high sensitivity, with a detection limit of 2.3, 3.7 and 4.4 ng/mL for AMO, AMP and CAR, respectively. The reaction conditions and the influencing factors were investigated, and the effects of coexisting substances were examined. This method showed a good selectivity in this work and is, therefore, recommended for application in the determination of penicillin antibiotics in capsule and tablet pharmaceutical formulations and human serum and urine samples.

TL;DR: In this article, a selenium-iodine enriched sugar made up by adding micro quantity of sodium selenite and potassium iodate to white sugar is presented, which can invigorate health of human body, and can prevent and cure the diseases caused by iodine deficiency.
Abstract: The present invention relates to a selenium-iodine enriched sugar made up by adding micro quantity of sodium selenite and potassium iodate to white sugar. The mixing ratio of selenium and iodine elements contained in said product is rational, and said product is easy to eat, and can invigorate health of human body, and can prevent and cure the diseases caused by iodine and selenium deficiency.

TL;DR: In this article, the spectra of nickel(II) and cobalt (II) ions dissolved in zinc chloride and zinc sulphate melts at temperatures between 350°-610° C showed a tetrahedral-octahedral coordination equilibrium, the octahedral species being favored by an increase in temperature and in zinc sulfate concentration.
