Colorimetric determination of potassium by Folin-Ciocalteu phenol reagent.
A method for the colorimetric estimation of manganese by reduction of the phosphomolybdicphosphotungstic acid phenol reagent has been described (Abul-Fadl, 1948). Cobalt was also found to give a similar colour reaction in the presence (but not in the absence) of amino-acids. Conversion of cobalt into the cobaltinitrite did not affect its response to this reaction. As methods for the estimation ...
متن کاملSpectrophotometric determination of ajmaline and brucine by Folin Ciocalteu’s reagent
A rapid and simple spectrophotometric procedure is described for the determination of ajmaline and brucine. The method is based on the development of blue coloured product due to reduction of tungstate and/or molybdate in Folin Ciocalteu’s reagent (FCR) by ajmaline and brucine in alkaline medium. The colour is stable for more than 48 h. The chromogenic reaction has max at 540 nm with molar abso...
متن کاملA novel spectrophotometric determination of caroverine in pharmaceutical formulations via derivatization with Folin-ciocalteu Phenol reagent.
In this study we have reported a new, fast and extraction free spectrophotometric procedure for the assessment of caroverine in pharmaceutical raw and tablet dosage forms. In the reported visible spectrophotometric procedure tungstate in Folin-Ciocalteu phenol reagent is reduced in alkaline medium and produces the blue colored chromogen that shows Λmax at 740nm with the calibration range of 2-2...
متن کاملIndentification of CWAs
The need for effective methods for the detection and measurement of chemical warfare agents (CWA) has increased in recent years. Current stockpiles need to be monitored to ensure their safe containment. The remediation of sites containing abandoned CWAs requires analysis in support of safe removal and destruction of agents. More recently, counterterrorism efforts have underscored the need for m...
متن کاملSystem Indentification with Artificial Neural Networks
A general approach for system identification with artificial neural networks is presented. A dynamic process can be represented as a function of the evolution of the inputs/outputs of the system. The standard approach to system identification is to describe the system by a set of equations that take into account the underlying mechanisms of the studied plant. If the equations of the system are ...
