To monitor chlorine content dissolved in water, Tabassum and Gupta developed an SPR based sensor making use of a 5 nm thick layer of conducting polymer polyvinylpyrrolidone (PVP) as the sensing element deposited over successive layers of silver (40 nm) and ZnO (10 nm) coated unclad core of...
11ai Weak intermolecular force of attraction between (hydrogen chloride) molecules requires little amount of heat energy to overcome the force 11aii11aiii When dissolved in water, HCl ionised to form H^+ and Cl ions. H^+ ions give the acidic property of solution.11bi A tangent is to be ...
A stirrer 9 is provided in the device 1 to mix and stir thoroughly the sample and water so that the chlorine is dissolved in water. The separated liquefied flon overflows from the mid-way of an overflow pipe 8 and is discharged through a sample overflow pipe 13 and a liquid level meter...
a compound of chlorine, such as sodium hypochlorite, that releases small quantities of chlorine gas when dissolved, used as bleach, a water disinfectant, and the like. chlorine词组 chlorine dioxide二氧化碳 chlorine gas氯气(等于 chlorine war gas) ...
using Cl and H2O as probes of the degassing process, we circumvent problems with traditional use of CO2and H2O (e.g. ref.4) that arise because extensively degassed, evolved magmas typically have very low dissolved CO2concentrations. Fig. 1: Chlorine degassing in arc volcanoes....
applying a bias of −0.1 V vs the reference electrode until 130 mC;cm−2of charge was passed. After rinsing with water the samples were dried with N2and then placed in a muffle furnace. 150 µL of 0.2 M vanadium acetylacetonate dissolved in DMSO was drop casted on each...
Chlorine content: Fifty g of a polymer was gasified and dissolved in water in accordance with Schoniger's methos, and the chlorine content was determined with a critical value of 0.05 ppm by ion chromatography (using Ion chrophatograph 2000i supplied by DIONEX K. K.). ...
The network parameters available included the water temperatures and chlorine concentrations at various locations in the network, the flow from the WTP, the dissolved organic carbon (DOC) content and Ultra Violet (UV) light absorbance at the WTP, and the time of each chlorine measurement. The lis...
corrosion to be fully eliminated regardless of Cl–crossover (Fig.4dand Supplementary Fig.22,23). As a sharp contrast, the anode is rapidly dissolved by high-concentration ClO–corrosion, inducing fast failure of ASE in only 6–7 h. Stable electrolysis can proceed below 0.36 V (...
