A new spectrophotometric method is proposed for the assay of ranitidine hydrochloride (RNH) in bulk drug and in its dosage forms using ceric ammonium sulphate (CAS) and two dyes, malachite (MAG) green and crystal violet (CV) as reagents. The method involves the addition of a known excess of ceric ammonium sulphate to ranitidine hydrochloride in acid medium, followed by the determination of unre...

The PVSDM model was used for single and binary dye adsorption systems. This is commonly in systems, but this the first time a mixture of dyes literature. To that end, new adsorbent derived from Bauhinia forficata waste created described eventual use treatment combination (methylene blue crystal violet). isotherms revealed increasing temperature decreases methylene capacity while violet capacity...

This study was undertaken to compare certain aspects of the colloidal behavior of ribonuclease treated bacterial cells with that of normal cells. Henry and Stacey (1943) and others have reported that ribonucleic acid plays an important role in gram staining. Many early investigators suggested that the electrical charge on the bacterial cell was an important factor in staining in general. If the...

The physicochemical characterization of the textile industry effluent collected from Oswal Textile Industries, Ludhiana (Punjab.) India has been carried out and the results showed that the temperature (40°C), pH (8.00), Biological Oxygen Demand (260 mgl –1 ), Chemical Oxygen Demand (790 mgl –1 ), Total Suspended Solids (2000 mgl –1 ), Total Dissolved Solids (7000 mgl –1 and colour over the pres...

Crystal violet treatment of formalin fixed paraffin embedded tissue slides greatly reduces the endogenous autofluorescence, and allows immunofluorescence (IF) staining with FITC or Alexa488 conjugated antibodies. Using cold CCD camera to capture the fluorescence images makes this staining method very sensitive. Here we show that combination of IF with the simultaneous recording of crystal viole...

Supramolecular polymerizations of 45- and 70- base DNAs on the surface of an in-situ time-resolved 27 MHz quartz crystal microbalance biosensor.

In this research, we discuss the removal of basic fusion (BF), and crystal violet (CV) dyes by strontium hydroxyapatite supported BiOI. a modified hydrothermal model, one can synthesize BiOI/SrHA. BiOI/SrHA was characterized using Fourier transform-infrared spectroscopy (FTIR), UV-visible (UV-vis) analysis, X-ray diffraction (XRD), energy (EDX), scanning electron microscopy (SEM). SEM outcome c...

The results of a study and application of leucocrystal violet for the determination of antimony in parts per million levels is described here. The proposed method is based on the reaction of antimony(III) with acidified potassium iodate to liberate iodine. The liberated iodine selectively oxidizes leucocrystal violet to crystal violet dye. The formed dye shows maximum absorbance at 590 nm. The ...

conclusions: it can be concluded that most of a. baumannii isolates can form biofilm in microtiter plate and tube. the results also verified that most of these isolates were resistant to ciprofloxacin and imipenem. results: results showed that in tube method under shaking, 22% of clinical isolates were strong biofilm producers while 23% of them were not able to form biofilms. in this experiment...
