  • Water analysis

    A complete tap water analysis includes the determination of the pH value, the alkalinity and the total water hardness. Both the pH measurement and the pH titration by means of a standard pH electrode suffer from several drawbacks. First, the response time of several minutes is too long and, above all, the stirring rate significantly influences the measured pH value. Unlike these standard pH ...

  • Buffering of Acidic Mine Lakes: The Relevance of Surface Exchange and Solid- Bound Sulphate

    Buffering mechanisms in an acidic mine lake in Lusatia, Germany were investigated. The titration curve has four sections with different buffering mechanisms: (1) buffering by free hydrogen ions and hydrogen sulphate (pH = 2.55-2.9), (2) buffering by Fe with bound SO4 (pH = 2.9-4.3), (3) buffering by Al with bound SO4 (pH = 4.3-5.5), and (4) buffering by surface exchange of SO4 and basic cations ...

  • Titrimetric determination of sulfate

    Most methods for the titrimetric determination of sulfate do not work reliably if interfering divalent cations such as calcium and magne¬sium are present in the sample. Using the methods described below calcium and magnesium will not interfere and can even be deter¬mined in the same analysis. IntroductionSeveral different titration methods are used to determine sulfate ...

  • Assessment of acid-base buffering properties of Flavoparmelia caperata: influence of age and pollution exposure

    This paper focuses on binding sites of lichens. The aim was to investigate the extracellular ionisable functional groups or binding sites that can play a (binding) ligand's role in young (peripheral) and older (central) thallus parts of the epiphytic lichens Flavoparmelia caperata collected under different pollution load environments. Potentiometric acid-base titration was used to obtain the ...

  • Analysis of adsorption equilibrium for aqueous solution of weak organic electrolyte-activated carbon system

    Several models for the adsorption of weak organic electrolytes on activated carbons from dilute aqueous solutions have been reported recently. It is apparent, however, that the electrokinetics of carbon surface has not been sufficiently addressed by these studies. The present treatment therefore employed the fundamental concepts provided by these studies, in conjunction with electrokinetic ...
