An emergency radiobioassay method for 226Ra in human urine samples.
A new radioanalytical method was developed for rapid determination of (226)Ra in human urine samples. The method is based on organic removal and decolourisation of a urine sample by a polymeric (acrylic ester) solid phase sorbent material followed by extraction and preconcentration of (226)Ra in an organic solvent using a dispersive liquid-liquid microextraction technique. Radiometric measureme...

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 اولRapid fluorometric estriol determination in pregnancy urine.
curves of precipitation are shown in Figure 1. Ampicillin, carbenicillin, amoxycillin, procaine penicillin, cephalothin, salicylic acid, acetylsalicylic acid, and dexamethasone caused no interference. The presence of methicillin in urine may be differentiated from the turbidity attributable to protein by measuring the absorbance at different intervals during the reaction, such as 0.5 and 5.0 mm...
متن کاملVoltammetric Determination of Sulfadoxine and Its Application in Pharmaceuticals and Urine Samples
The voltammetric behaviour of Sulfadoxine (SDN) was studied at a glassy carbon electrode in 0.2 M phosphate buffer solutions using cyclic, differential-pulse (DPV) and square wave voltammetry (SWV). The dependence of the current on pH, concentration, and scan rate was investigated to optimize the experimental conditions for the determination of SDN. The oxidation process was shown to be diffusi...
متن کاملFlow Injection Spectrophotometric determination of Doxorubicin Hydrochloride in Urine samples
A simple and fast FI colorimetric procedure for determination of doxorubicin hydrochloride (DXH) was proposed. It is based on the redox reaction between iron (III) and DXH, resulting in an intensely red colored complex in the presence of 1, 10-orthophenantroline which can be followed by spectrophotometric measurement at λmax= 510 nm. This is an automatic way to determine doxorubicin hydrochlori...
