The key stages of this approach are: (1) etching of residual products with dilute HCl; (2) carbon dioxide treatment with microwave plasma induction at 950–1000 ○С; and (3) thermal shock. The sequential application of procedures (1)–(3) to the residual products of carbon dioxide ...
What happens when freshly prepared FeC3 is shaken with dilute FeC3 solution? View Solution What happens when white precipitate of Bi(OH)3 is boiled ? View Solution What happens when ferrimagnetic Fe3O4 is heated to 850K? View Solution What happens when silver sulfide is shaken with NaCN so...
Studies on supported liquid membrane for simultaneous separation of Fe (III), Cu (II) and Ni (II) from dilute feed A polymer inclusion membrane (PIM) is reported consisting of 45% (m/m) di(2-ethylhexyl)phosphoric acid (D2EHPA) immobilized in poly(vinyl chloride) (PVC) f... Gill,J....
Before analysis, samples were thawed and diluted with dilute nitric acid, and the Fe concentration was determined by inductively coupled plasma-mass spectrometry. Analysis of Fe adsorption and desorption kinetics. The Fe adsorption and desorption kinetics were analyzed as described earlier in Jin ...
配置不同浓度Fe3+溶液时,使用HCl溶液调节溶液pH相等,并通过添加分析纯NaCl试剂使溶液中Cl-浓度尽量相近。不同浓度Fe3+溶液中304不锈钢腐蚀的动电位极化曲线如图1所示,其拟合结果列于表2中。由图可知,当pH为1.64,Cl-浓度为0.3 mol/L时,随着Fe3+浓度的增加,304...
The activities of water of the H2SO4-Fe2(SO4)3-H2O solution system were determined by an isopiestic method and those of HCl-FeCl3-H2O by a transpiration method both at 298 K. The experimentally determined water activities satisfactorily obeyed the Zdanovskiirule. The activities of water ...
You have 26.44 ml of 1.83 M HCl in a beaker. You dilute this acid with 40.08 ml of water. When you analyze the solution you find that the number of moles of HCl in the new solution is ___. How many moles of KNO3 are needed to make 600 mL of a ...
alkaloids presence in the KI extract was revealed if a white or green precipitate appears on addition of few drops of Mayers reagent into a mixture containing 2 mL each of the KI extract and dilute hydrochloric acid32. In order to determine the presence of saponins, about 0.2 g of KI leave...
First, 98.67% of the co-extracted iron in the loaded organic phase was scrubbed with a dilute HCl solution by a three-stage counter-current scrubbing. Then, 85.00% of Sc(III) can be stripped efficiently with a 2-mol/L NaOH solution saturated in 1-mol/L NaCl by three-stage cross-...
Note that the concentration of Fe3O4@PDA dispersions was determined based on the Beer–Lambert law, which declared that the absorbance of a dilute solution was proportional to its solute concentration. In addition, the introduction of organic PDA might also contribute to the absorption of optical...
