Chemical Modification of Nanosilica Toward Dispersive Solid Phase Extraction of Trace Triazine Herbicides from Environmental Water Samples
An easy and fast pathway in preparation of organo-functionalized silica in nanosize range withphenyl-terminated group via co-condensation method is reported. Fourier transform infrared(FTIR) spectra confirmed the grafting process and scanning electron microscopy (SEM) imagecorroborated formation of nanosized material. Applicability of phenyl-modified nanosilica wasexamined as a sorbent in dispe...

ساخت الکترودهاِی اصلاح شده ِیکِی از چالشهاِی همِیشگِی در دانش شیمِی بوِیژه شیمِی تجزیه مِی باشد ،که با در نظر گرفتن سادگِی ساخت، کاربردی بودن و ارزان بودن روش مِی توان به باارزش بودن چنِین سنسورهاِی پِی برد.آنچه که در ادامه آورده شده به ساخت و کاربرد الکترودهاِی اصلاح شده با استفاده از نانو ذرات در اندازه گِیرِی ولتامترِی آهن وکادمِیم اشاره دارد. کار اول اختصاص دارد به ساخت الکترود خمِیر کربن اصلاح شده با لِیگاند داِ...
15 صفحه اولMajor inorganic elements in tap water samples in Peninsular Malaysia.
INTRODUCTION Quality drinking water should be free from harmful levels of impurities such as heavy metals and other inorganic elements. METHODS Samples of tap water collected from 24 locations in Peninsular Malaysia were determined for inorganic element content. Minerals and heavy metals were analysed by spectroscopy methods, while non-metal elements were analysed using test kits. RESULTS M...
متن کاملApplication of Magnetite Nanoparticles in Phenylalanine Removal from Water Samples
The purpose of the current research is investigating the phenylalanine removal by using magnetic nanoparticles (Fe3O4) from water samples. The effect of pH, contact time and phenylalanine concentration on phenylalanine adsorption efficiency by magnetite nanoparticles are studied in a batch system. Transmission electron microscopy (TEM), X-ray Diffraction Patterns (XRD) and...
متن کاملDerivative Spectrophotometric Determination of Trace Amounts of Tungsten (vi) in Real Water Samples
2,4-Dimethoxybenzaldehydeisonicotinoylhydrazone (DMBHIH) has been synthesized and characterized with IR, NMR and Mass Spectroscopic methods. A simple and derivative spectrophotometric method has been developed for the determination of trace amounts of W (VI). The reagent forms an yellow coloured water soluble complex with W (VI) in bacic medium (pH 8.0). The molar absorptivity and Sandell’s sen...
