A new bispyrenyl azadiene derivative has been synthesized and examined for its cation recognition abilities toward different cations. The ligand shows strong affinity for Hg(2+) ions over other cations such as Cu(2+), Pb(2+), Zn(2+), Ni(2+), Cd(2+), Ag(+), K(+), Na(+) and Li(+). An "Off-On" type of fluorescent behaviour was observed with simultaneous presence of Cu(2+) and Hg(2+) ions. An ion s...

Introduction and purpose: The olive oil industry wastewater contains significant amounts of oil and this can cause serious problems if it is discharged into the wastewater treatment system, so the oil in the wastewater must be removed and seperated prior to any action. Therefore, the oil in the sewage should be removed and separated prior to taking any measure. There are several ways to remove ...
a flow injection method is reported for the determination of ascorbic acid based on amperometric detection, using a cobalt(ii) phthalocyanine (copc) modified graphite-epoxy electrode. the amperometric respons was evaluated with regard to ph, ionic strength of the electrolyte, flow rate of the carrier solution, injected sample volume and conditioning time of the electrode. the limit of detection...

choline oxidase (chox) was chosen as a model enzyme for evaluating the performance of cnts’ functional groups for development of enzyme electrodes. cnts were functionalized with carboxylic acid, amine or amide groups. carboxylic acid, amine and amide functionalized cnts were obtained by acid treatment, ethylenediamine or tetraethylenepentamine chemically modification and ammonia plasma treatmen...
presently there are a number of fine and sensitive methods for determining chemical or biochemical substance among which bio electrodes represent the most recent development. bioelectrodes consist of biologically active materials (e.g enzyme, antibody, whole cell or cell fragments) held in close proximity to a suitable electrochemical transducer that sense specific electroactive enzyme substrat...
Irradiated suspensions of sem~ single crystal and polycrystalline conductor powders, e.g., Ti02, have semiconductor materials currently been employed in such heterogeneous being investigated. Measurements photo processes as the oxidation of involving such slurry electrodes cyanide, the decomposition of carare of use not only for the charboxylic acids, and the deposition acterization of the powd...
Objective: In neural response telemetry, intracochlear electrodes stimulate the auditory nerve and record the neural responses. The electrical stimulation is sent to the auditory nerve by an electrode and the resulted response, called electrically evoked compound action potential, is recorded by an adjacent electrode. The most important clinical applications of this test are evaluation and moni...
