Unusual Identification of Explosive
Sir,?In the September issue, 1935, of your esteemed journal it has been mentioned, on page 506, by Dr. N. J. Vazifdar, that after a bomb explosion 'arsenic' enters into the system through the wound and also by inhalation of arsenuretted hydrogen which is evolved in the explosion. A bomb of the type under discussion explodes due to the interaction of sulphide of arsenic with an oxidizing agent s...
متن کاملDevelopment of a Quantitative Edxrf Method for Determining the Concentration of Palladium Applied to Tobacco
A quantitative energy dispersive X-ray fluorescence (EDXRF) spectrometry method was developed for determining the concentration of palladium (Pd) applied to tobacco cut filler. Control and standards were created in-house with different levels of Pd concentration. After application of the Pd in a salt solution, the tobacco had an average oven volatiles (OV) value of 27.6%. Three aliquots were an...
متن کاملDetermination of soluble toxic arsenic species in alga samples by microwave-assisted extraction and high performance liquid chromatography-hydride generation-inductively coupled plasma-atomic emission spectrometry
A microwave-based procedure for arsenic species extraction in alga samples (Sargassum fulvellum, Chlorella vulgaris, Hizikia fusiformis and Laminaria digitata) is described. Extraction time and temperature were tested in order to evaluate the extraction efficiency of the process. Arsenic compounds were extracted in 8 ml of deionised water at 90 °C for 5 min. The process was repeated three times...
متن کاملمعرفی، بلورشناسی و پیدایش کانی اریثرایت (Co3(AsO4)28H2O) در نشانه معدنی تاریکدره، شمال شرقی ایران
Erythrite (Co3 (AsO4)28H2O) is one of the rare arsenic minerals which belong to the vivianite group. A recent discovery in Tarikdarreh prospect area (northeastern Iran) found erythrite along with scorodite and hydroxides of iron have been recognized as a supergene alteration product of primary arsenic mineral in surface arsenopyrite ± pyrite mineralization veins zones. A specimen of erythrite h...
متن کاملUsing Ghezeljeh Nanoclay for Measuring of Copper Ions Released from the Cooking Pot into Food Samples by FAAS and ICP-AES
Ghezeljeh montmorillonite nanoclay was used as a natural adsorbent to measure and remove copper ions released from the cooking pot into food by applying the solid phase extraction (SPE) method in batch mode. The clay is characterized by using fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and X-ray diffractometry (XRD). The results of XRD and FT-IR of n...
