Surfactants Analysis from Natural Waters Using Nonfaradaic Processes
Voltammetric measurements of dissolved surface-active substances in aqueous solutions, as specific commercial detergents, are described in the present paper. Two voltammetric methods based on the adsorption phenomena at mercury electrode/aqueous solution interface were performed in order to obtain the analytical signal for the detergent analysis. The first method was direct current polarography...
متن کاملRendering Natural Waters
Creating and rendering realistic water is one of the most daunting tasks in computer graphics. Realistic rendering of water requires that the sunlight and skylight illumination are correct, the water surface is modeled accurately and that the light transport within water body is properly handled. This paper describes a method for wave generation on a water surface using a physically-based appro...
متن کاملNatural Phonological Processes in Sistani Persian of Iran
This article provides an overview of natural phonological processes in the dialect of Sistani Persian spoken in Iranian Sistan, and reviews theoretical implications of these processes. A representative selection of processes in the language is examined in reference to conditioning by surrounding segments and conditioning in reference to syllable structure. While assimilation and dissimilation a...
متن کاملVoltammetric measurement of arsenic in natural waters.
There are several U.S. EPA approved methodologies for the determination of arsenic in ground water. Such technologies are lab-based, time intensive and can lead to a large capital cost for multi-sample analysis. In light of the number of sites found to contain arsenic at levels higher than the maximum contaminant level (MCL), on-site screening and monitoring systems are an attractive alternativ...
متن کاملSpeciation of metals in natural waters
The form or speciation of a metal in natural waters can change its kinetic and thermodynamic properties. For example, Cu(II) in the free ionic form is toxic to phytoplankton, while copper complexed to organic ligands is not toxic. The form of a metal in solution can also change its solubility. For example, Fe(II) is soluble in aqueous solutions while Fe(III) is nearly insoluble. Natural organic...
