A silica based amino stationary phase was prepared by immobilization of propargylamine on azide-silica via click chemistry. This readily prepared click amino stationary phase demonstrated good selectivity in separation of common inorganic anions under ion chromatography (IC) mode, and the triazole ring in combination with free amino group was observed to play a major role for separation of the ...

Major components of inks have molecules that are vibrationally active and thus give infrared spectra. These components are related to both the type of ink involved, and they are part of a total system, along with possible metal ion-based molecules, that make up the chemistry of inks. In this proposed study, modern synchrotron radiation-based---as well as conventional---infrared spectroscopy wil...

Groundwater has been the main resource used for drinking, domestic and agricultural activities in West central Senegal past few decades. Thus, this study investigates quality of groundwater assesses its suitability drinking irrigation purposes. To end, 42 samples were collected analyzed various chemical parameters (major ions, fluoride, pH, total dissolved solids (TDS)). Chemical data interpret...

Wadi El Raiyan is a great depression located southwest of Cairo in the Western Desert of Egypt. Lake Qarun, located north of the study area, is a closed basin with a high evaporation rate. The source of water in the lake is agricultural and municipal drainage from the El Faiyum province. In 1973, Wadi El Raiyan was connected with the agricultural wastewater drainage system of the Faiyum provinc...

Chemistry can influence dose rates by two aspects: chemistry conditions applied in the primary circuit and removal of (in)soluble particles. Since coolant activity have a significant impact on area personnel doses, main objective purifying is to act radioactive source keep it as low reasonably achievable. Reduction occupational exposure maintains confidence among workers public. Other factors, ...

The Yellow River has played an indispensable role in supporting Chinese civilization because it provides water resources and rich soil for agriculture. This study analyzes the major ions isotopic ratios of hydrogen (δD), oxygen (δ18O), carbon (14C) groundwater samples to identify sources recharge impact on Changqing-Xiaolipu karst aquifer. ion/Cl− generally follow mixing line between southern m...

Carbon nanotube (CNT) membranes allow the mimicking of natural ion channels for applications in drug delivery and chemical separation. Double-walled carbon nanotube membranes were simply functionalized with dye in a single step instead of the previous two-step functionalization. Non-faradic electrochemical impedance spectra indicated that the functionalized gatekeeper by single-step modificatio...

Soldi-Lose Héloïse: Gas-Phase Ion and Radical Chemistry of CO2 Adducts with Possible Relevance in the Atmosphere of Mars In the Mars atmosphere, reactivity of trace components is as relevant as that of the major compounds if formation of complex molecules is considered. These are of great importance concerning the existence of a past or future life on Mars. In this context, the gas-phase chemis...
