A differential pulse voltammetric method was described for the determination of domperidone. The method was based on the anodic oxidation of domperidone on a glassy carbon electrode at +0.64 V vs. SCE in Britton-Robinson buffer solution of pH 2.3. The reversibility of the oxidation was tested by cyclic voltammetry; the electrode process is irreversible and(More)
The adsorption behavior of cefonicid on the hanging mercury drop electrode (HMDE) has been examined using cyclic voltammetry and square-wave voltammetry techniques in Britton-Robinson (B-R) buffers in the pH range of 2.0-11.0. The effect of different parameters on the accumulation behavior of the adsorbed species has been evaluated. Sensitive measurements(More)
A hundred and fifty samples of fish rations were collected and subjected to mycological examination. The total prevalence of Aspergillus flavus was 66.67%. Fifteen isolates among them were aflatoxinB1 producers. AFB1 was extracted and tested for pathogencity. AFB1 intoxicated fish showed off feed, sluggish swimming, dark skin, loss of reflexes, increased(More)
