Shah, Devendra D. Prajapati, Krupa R. Synthesis of fluorohydroxyquinolinecarboxylic acids by the Gould—Jacobs reaction.DOI: Studies on Antibiotics Active against Resistant Bacteria. Organic Letters , 17 17 , Siva S. Panda, Sumaira Liaqat, Adel S. Girgis, Ahmed Samir, C. Dennis Hall, Alan R. The degree to which zinc sulfide clusters were adsorbed on membrane filters during filtration was mitigated if the clusters were synthesized in the presence of natural organic matter. Examples of AVS and CRS concentrations determined in oxygenated waters using the PT method were comparable to those reported recently by other methods. This method offers greater simplicity than other methods for trace dissolved sulfide determination in natural waters. Keywords: Sulfide; Purge-and-trap; Methylene blue; Chromium reduction; Oxic waters; Natural organic matter; Simplified version of the sodium salicylate method for analysis of nitrate in drinking waters by M. Monteiro; F. Ferreira; N. The salicylate method for determination of nitrate in drinking waters has been simplified by using the calibration solutions for 54 days, and therefore, reducing the work time. The results obtained can be considered satisfactory with regard to limit of determination 0. Keywords: Nitrate determination; Spectrophotometric method; Salicylate method; Water; Speciation analysis of mercury in seafood by using high-performance liquid chromatography on-line coupled with cold-vapor atomic fluorescence spectrometry via a post column microwave digestion by Li-Na Liang; Gui-Bin Jiang; Jing-Fu Liu; Jing-Tian Hu An automatic system, based on the on-line coupling of high-performance liquid chromatography HPLC separation, post column microwave digestion, and cold-vapor atomic fluorescence spectrometry CVAFS detection, was proposed for the speciation analysis of four mercury compounds. Post column microwave digestion, in the presence of potassium persulfate in HCl , was applied in the system to improve the conversion efficiency of three organic mercury compounds into inorganic mercury. Parameters influencing the on-line digestion efficiency and the separation effect were optimized. To avoid water vapor and methanol entering into the atomic fluorescence detector, ice—water mixture bath was used to cool the microwave-digested sample solution. Seafood samples, composed of three gastropod species and two bivalve species from Yantai port, China, have been analyzed by the proposed method.

At several concentrations of oxolinic acid chitosan microspheres had different external morphology, by means of SEM was observed that a high concentration of antibiotic generated smooth external texture, where most of them were spherical shape. The solubility of chitosan microspheres was very low in sea and nanopure water, since the protonation at basic pH of chitosan amino group was very low, the solubility was lower than diluted acetic acid. The solubility of chitosan at different concentrations of antibiotic microspheres showed a Gaussian tendency of solubility at different acid pH ranges hydrogels. The optimum pH of chitosan spheres solubility occurred at pH 3. Chitosan microspheres had different concentrations of oxolinic acid, because releasing of antibiotic concentration may occur and which was measured by the HPLC method. The release of oxolinic acid on chitosan microspheres was faster at pH 5. Chitosan microspheres had an average dry weight of 1. However, these achievements are accompanied by the increase of several problems, such as the emergence of fish diseases. This is, at present, the most frequent application of microencapsulation. The variety of materials that can be used in microencapsulation is being gradually extended, emerging new biomaterials and new applications. In general, is able to use micro materials that are classified into three categories: fats, proteins and polymers. There are several methods of synthesis such as: coacervation, interfacial polymerization, extraction with evaporation of the solvent, spray and atomization-freezing, suspended in air and ionic gelling. The main goal of this work was to get a high effectiveness in the administration of antibiotic within salmon farms in order to decrease the elevated amount used during the different growing stages. All this stage must have a duration of 90 minutes. Once chitosan was obtained, it was washed with hot water to remove remaining NaOH and finally dried at room temperature. The difference of weight gives the ashes percentage [ 12 , 13 ]. Franzblau, Kelly Chibale.
