95, No. We have developed a simple method for the selective colorimetric detection of aqueous mercuric (Hg2+), silver (Ag+), and lead (Pb2+) ions by using label-free gold nanoparticles (Au NPs) and alkanethiols. The aim of this study is to determine the measurement uncertainty of spectrophotometric determination of Cr(6+) in water. Trace determination of heavy metals is one of the most important issues of chemical analysis [1].

The problem of heavy metal pollution arises from several sources. The heavy metals data of the water sample collected in … etc.) In the proposed method, trace metal ions in aqueous samples were adsorbed by cation exchange fibers and desorbed by acidic solution from the fibers. Ayodele Rotimi Ipeaiyeda and Olayinka Jumoke Asagunla Orhan Turkoglu. Soils Nasirudeen* and A.U. Thus This corresponds to Ross (1994) who suggested that contamination of agricultural soils with heavy metals through irrigation water is primarily due to irrigation water sourced from deep wells or polluted rivers, lakes and channels. Water samples were filtered Metals in water and wastewater may be present in any or all of the following forms, each of which may require determination: (a) Dissolved (filterable) metals: Those metals which pass through a 0,45 ym membrane filter. The method is based on the reaction of arsenic(III) with potassium iodate in acid medium to liberate iodine, which oxidizes variamine blue to form a violet coloured species having an absorption maximum at 556 nm. Over the years, UV-Vis spectrophotometry has been widely used for the determination of metals [2-6], because it is an available and inexpensive technique which can be found in most laboratories.

In order to understand the heavy metal concentration from wastewater, it is desired to have effective, accurate but simpler and low cost method for heavy metals. Lemos VA(1), dos Santos LO, Silva Edos S, Vieira EV. Spectrophotometry is essentially a trace analysis technique and is one of the most powerful tools in chemical analysis. The reagent reacts with arsenic in acidic medium (pH 5.0, ... methods were used for the quantitative analysis of heavy metals in all samples. In the proposed method, trace metal ions in aqueous samples were adsorbed by cation exchange fibers and desorbed by acidic solution from the fibers. Mercury and cadmium can be a result of power plant emissions. Three automated flow-injection systems are proposed for the determination of traces of manganese(II), lead and copper(II) in waters.
