The high quality thin films of (CdS)0.6 Se0.4 have been synthesized using thermal evaporation technique onto precleaned rotating amorphous glass substrate at room temperature. The films were characterized by X-Ray Diffractometer, Scanning Electron Microscopy, Atomic Force Microscopy and UV-VIS Spectrophotometer. The XRD spectrum illustrates that the films are polycrystalline having hexagonal st...

Abstract Background In TB, therapeutic drug monitoring (TDM) is recommended for linezolid; however, implementation challenging in endemic settings. Non-invasive saliva sampling using a mobile assay would increase the feasibility of TDM. Objectives To validate linezolid UV spectrophotometer. Methods The was developed NanoPhotometer NP80® and concentrations were quantified second-order derivative...

present study dealt the removal of cr(vi) in a tannery industry wastewater using rice husk silica powder as an adsorbent.the experimental investigations have been carried out by using rice husk silica powder for different adsorption dosage, different contact time and different ph against the initial cr(vi) concentration of 292 mg/l. the maximum percentage removal of cr(vi) in the tannery indust...

The UV-visible diode array spectrophotometer is a work-horse instrument for many laboratories. This article provides simple data acquisition and control routines in Microsoft QuickBasic for a HP-8452A diode array spectrophotometer interfaced to an IBM PC/XT/AT, or compatible, microcomputer. These allow capture of full spectra and measure absorbance at one or several wavelengths at preset time i...

In this data article, we determined the concentration levels of heavy metals including Pb, Co, Cd, Mn, Mg, Fe and Cu as well as selected anions including [Formula: see text] , [Formula: see text], [Formula: see text] and [Formula: see text] in the most used and popular herbal distillates in Iran. It is well known that heavy metals may pose a serious health hazard due to their bioaccumulation th...

Ultraviolet UV absorbance measurements are subject to significant error using a standard spectrophotometer when particles or aggregates that scatter light are present. True UV absorbance for highly turbid waters should be measured using integrating sphere IS spectrophotometry that allows the collection of reflected and transmitted radiation simultaneously. This is especially important when the ...
