  • Expanded HPLC Method for N-Methyl Carbamates post-column analysis of pesticides in food and potable water samples

    Carbamate pesticides are widely used around the world to protect crops. In addition, they are used as biocides for industrial or other applications and in household products. Though carbamates are biodegradable compounds and bioaccumulation usually happens only to a low extend it is important to monitor produce to make sure enough time has elapsed between harvest and applying pesticides. Also, ...

  • Effects of current density on copper nanoparticle prepared by electrochemical method

    Copper nanoparticles are prepared by electrochemical method with various current density in emulsion containing sodium dodecyl sulfate, tween80, dodecyl mercaptan, CuSO4 5H2O. The resulting copper nanoparticles are investigated by XRD, TEM and FT-IR. The result shows that great changes have taken place in the size, the dispersibility, and the distribution of particles size as the current density ...

  • o-Phthalaldehyde Reagent

    Introduction Primary amines form highly fluorescent adducts when reacted with o-Phthalaldehyde (OPA) and a mercaptan under basic conditions. At a pH>9 and ambient temperature, reaction is generally complete within 30 seconds. The products of this reaction, 1-alkyl-2-alkylthio-substituted isoindoles, exhibit optimal excitation at 330 nm and maximal emission at 465 nm. The reagents ...

  • Case study - Corrosion protection in a pulp and paper industry

    It is widely accepted that corrosion has an important economic impact at an industrial scale. As an example, results of a study carried out in the US showed that the total annual estimated direct cost of corrosion in the country was $276 billion, which was approximately 3.1% of the nation’s Gross Domestic Product (GDP). Thus, within the last few decades, an important effort has been made to ...
