An Optical Chemical Sensor For Monitoring Of Nickel In Waters And Hydrogen Peroxide Samples

Abstract

Application of nickel in different industries has been developed and so contamination of natural water is a great concern due to its potentially toxic effects on living beings. Therefore, fast monitoring of Ni ). The precision (relative standard deviation) was better than 1.55% for 7 replicate determinations of 17.10 µmol L -1 of Ni in various membranes.

Use of dimethylglyoxime for the spectrophotometric flow-based determination of nickel in natural waters

“…Nickel is considered an essential element for animals, being its deficiency associated with an altered liver functioning. However, exposure to high levels of this metal (metallic nickel or nickel soluble or less soluble compounds) is associated with human harmful effects, such as allergic reactions, asthma, lung cancer and leukaemia [12,14].…”
