The vibrational spectral analysis was carried out by using FT-Raman and FT-IR spectroscopy in the range 4 000~400and 4 000~400cm-1 respectively,for N-[4-[1-hydroxy-2-[(1-methyl ethyl)amino]ethyl]phenyl]methane sulfona...
Interest in preconcentration techniques for the determination of metals at ultratrace levels still continues increasingly because of some disadvantages of flameless atomic absorption spectrometry as well as the high c...
