Membrane Sensor Polyvinyl Chloride with Immobilization Dithizone for Determination of Nickel (II) Ion
نویسندگان
چکیده
Abstract A simple analytical method, cheap and biologically friendly, to find Ni (II) in drinking water was developed by dithizone immobilization chloride polyvinyl matrix (PVC) dioctyl phthalate as plasticizers. Nickel is a toxic dangerous metal for humans the environment. The step experimented with making membrane sensor next characterization of UV-Vis spectrophotometry, atomic absorption spectrophotometry (AAS), SEM. ion has caused change color from green brownish red maximum 418 nm optimum response gaining on pH 8,8. proposed size 1 x 2 cm, sample volume ml 0 - 0.06 ppm concentration range. method that had been applied determining after addition standard solution recovery 82.93-109.49 % while measurements obtained 104.11-107.96 %. contained cannot exceed regulation quality PERMENKES RI No: 907/KEMENKES/PER/VII/2010.
