After chlorophylls measurement, the pigment ethereal solution was dried and saponified using a KOH methanolic solution.
All measurements were performed in triplicate, the absorbance was measured in 1 cm cuvettes, and for calibration solutions and blank preparation, a methanolic solution at the same concentration as the samples was used.
A methanolic solution of the metal salt was added gradually to a methanolic solution of the phenolic hydrazone (H2L) in the mole ratio 1 : 1; metal ion : ligand.
TEM sample was prepared by dropping a methanolic solution containing a well-dispersed composite on a carbon-coated copper grid.
A methanolic solution of VOSO4.H2O was added gradually to a methanolic solution of the phenolic hydrazone in absence (complex 1) and in presence of Oxine, Phen or Tmen (complexes 2-4) athehe mole ratio 1: 1: 1.
In this study, the BmimBF4 ionic liquid was substituted by a methanolic solution of HF and a high boiling point alcohol acting as a solvent (benzyl alcohol).
Following this elution step the colourless ARTS are detected by spraying with either a methanolic solution of DNP or FBS which produce the coloured spot.
A methanolic solution of 2,2-dithiodipyridine (aldrithiol) (45.5 mM, 0.5 equiv) was added to the solution.
This material was then immersed in a methanolic solution of phosphotungstic acid (H3PW12O40).
For this purpose, a methanolic solution of 3 was mixed with Na2HAsO4 ⋅7 H2O (2 equiv).
