TL;DR: A new method for the quantitive determination of sialic acids is described, which is about 50% more sensitive than the orcinol-hydrochloric acid method generally used and considerably lower with the resorcin reagent.

TL;DR: In this article, the effect of oxidation on the structural integrity of multiwalled carbon nanotubes through acidic (nitric acid and a mixture of sulfuric acid and hydrogen peroxide) and basic (ammonium hydroxide/hydrogen peroxide), agents has been studied.

TL;DR: Freedom from interferences under the chosen experimental conditions as well as the good results obtained for recovery and precision indicate that the methods are suitable for monitoring inorganic, organic and total phosphorus in sediments.
Abstract: A simple, rapid and semi-automated method for the determination of inorganic, organic and total phosphorus in lake and river sediments is described. Total phosphorus is extracted from sediments with 1 N hydrochloric acid after ignition at a high temperature (550 °C) or by digestion with sulphuric acid-potassium persulphate at 135 °C in a sealed PTFE-lined Parr bomb. Organic phosphorus is determined by the difference in phosphorus content of the 1 N hydrochloric acid extract measured before and after ignition of the dry sediments at 550 °C. In all instances the orthophosphate is determined by using standard Technicon AutoAnalyzer II techniques. The interferences caused by silica and variable acid concentrations on the determination of phosphorus have been studied. Freedom from interferences under the chosen experimental conditions as well as the good results obtained for recovery and precision indicate that the methods are suitable for monitoring inorganic, organic and total phosphorus in sediments.

TL;DR: In this article, the corrosion inhibition of mild steel in 1-M hydrochloric acid solution by some 2,5-bis n -thienyl)-1,3,4-thiadiazoles (n -TTH) has been studied in relation to the concentration of the inhibitors as well as the temperature using chemical (weight loss) and electrochemical (ac impedance and dc polarisation) techniques.

Journal ArticleDOI
TL;DR: In this article, the electrochemical behavior of magnesium was studied in representative chloride and sulphate solutions including NaCl, Na2SO4, NaOH and their mixed solutions, HCl, and H2SO 4: (1) by measuring electrochemical polarisation curves, (2) by using electrochemical impedance spectroscopy (EIS), and (3) by simultaneous measurement of hydrogen gas evolution and measurement of magnesium dissolution rates using ICPEAS.
