3d). Furthermore, the band at room temperature was not detected in experiments carried out with only iron (III) chloride and attenuated and shifted to the left with only iron (II) chloride for the NaOH concentration set at 0.15 M, and recall under N2 atmosphere to minimize as much as ...
All other reagents such as glutaraldehyde (GA), ammonium iron (II) sulfate hexahydrate, methyl acrylate, ethylenediamine (EDA) and thionyl chloride were of analytical grade and purchased from Sinopharm Chemical Reagent Co. Ltd. (Shanghai, China). Analysis of the 3D-structure of BCL The 3D ...
Lignin phenols in the freeze-dried water-extracted soils, CBD-OM precipitates and CBD-treated residues of soils (<53 μm) were analysed using CuO oxidation method70,71. Briefly, dried soils or OM were mixed with 1 g CuO, 100 mg ammonium iron (II) sulfate hexahydrate and 15 ml...
6.7 ml of 1-molar iron(III) chloride hexahydrate solution are prepared in a test tube and degasified using nitrogen. 648 mg of iron(II) chloride tetrahydrate are added to the iron(III) solution and dissolved in the nitrogen stream. The polymer solution is heated to ca. 75° C., and ...
