Application of Derivative Spectrophotometry to Determine the Relation Between Color Intensity and Dye Concentration of Madder
The Derivative Spectrophotometry usually improves resolution bands, eliminates the influence of background and provides more defined fingerprints than original spectra, hence enhancing the detectability of minor spectral features. In this work, different madder types were collected and applied for dyeing woolen yarns used in Persian carpet in conventional pre-mordanting and dyeing process with ...
متن کاملApplication of the 1,2-Dihydroxybenzene-3,5-Disulfonic Acid for Separation and Preconcentration of Trace Iron and Determination by Eight Order Derivative Spectrophotometry
Iron is quantitatively retained on an adsorbent made by coprecipitation of 1,2-dihydroxybenzene-3,5-disulfonic acid (Tiron) and tetradecyldimethylbenzylammonium choride (TDBA) an microcrystalline naphthalene as a slurry or packed in a column, in the pH range 6.0-9.0 from a large volumes of aqueous solutions (up to 200 ml on microcrystalline naphthalene and up to 500 ml of aqueous solutions ...
متن کاملSimultaneous Determination of Losartan and Hydrochlorothiazide in Pharmaceutical Preparations by Derivative and Ratio Derivative Spectrophotometry
Background & Aims: Losartan is a non-peptide potent antihypertensive agent that acts through blocking angiotensin II receptors. Hyzaar® is a combination product that contains two drugs, losartan and hydrochlorothiazide, used to lower high blood pressure. There are some reports regarding simultaneous measurement of the drugs in pharmaceutical and biological samples which includes HPLC, CE, CEC, ...
