Therefore, the data shows that induced dipoles play an important role in the absorption coefficient in the frequency region dominated by intermolecular librational dynamics, and

The method applied for the extraction of the thiabendazole and imazalil residues from lemons was based on the analytical method described for the determination of these fungicides

Comparing with phosphole it can be concluded from these results that, the inclusion of another phosphorus and an arsenic atom in the five membered rings reduces the energy barrier

Minimum inhibitory concentration (MIC) was determined by the dilution method according to NCCLS (National Committee for Clinical Laboratory Standards) procedure.. Keywords :

SiO 2 /ZrO 2 mixed oxide obtained by a sol-gel processing method adsorbs Sb(V) from acid solution forming a phase, not characterized, on the matrix surface. The Br φ nsted acid

pH measurements were carried out on Metrohm Herisau pH-meter using Scott Gerate glass combination electrode. Stoichiometric points were obtained from the sharp inflections in

The replacement of the Cu(II) ions for Fe(II), Mn(II) and Cd(II) does not eliminate the absorption band at 425 nm, supporting its assignment as a charge-transfer transition
