zataria multiflora essential oil, hydrogen peroxide(h2o2) and malachite green (mg) were used to assess their effects on rainbow trout egg hatchability and survival of larvae up to 1-1.2 g body weight using spring water at 12.5 °c, dissovled oxygen 8-9 mg/l, carbon dioxide 7±2 mg/l, ammunia

The use of a novel inexpensive photometric device, a paired emitter-detector diode (PEDD) has been applied to the colorimetric determination of phosphate using the malachite green spectrophotometric method. The novel miniaturized flow detector applied within this manifold is a highly sensitive, low cost, miniaturized light emitting diode (LED) based detector. The optical flow cell was construct...

The classical malachite green (MLG) assay of phosphate, which added MLG after molybdate to the acidified reaction solutions of phosphate, tolerated interference from papaverine, sildenafil, and some similar hydrophobic amines. Resonance Rayleigh scattering signals, the alleviation of interference by poly(vinyl alcohol), and the precipitation of some yellow complexes supported that the irreversi...

In order to see the influence of different variable parameters (initial pH of the solution, Fe++ concentration and H2O2 concentration) and the efficiency to remove Malachite Green dye (Basic Green 4) from aqueous solution, Fenton Oxidation method was employed. Then different parameters were studied using known concentration (150 mg/l) and initial COD (256 mg/l) of prepared dye synthetic solutio...
