The molar conductance of the complexes was measured using freshly prepared 10-3 M solutions in electrochemically pure DMF at room temperature, using a Conductometer
pH Meter, Conductometer
, Double beam spectrophotometer, Fume Hood.
20 Minutes later, residual content of metal ions was determined on the KFK-3-01 conductometer
(LLK ZOMZ, Russia) with use of the photometrical method [26, 27].
Conductivity Electric conductivity of emulsion could be measured at ambient temperature with digital conductometer
pH and conductance were measured using Inolab pH and cond 720 WTW series pH meter and conductometer
1], measured with a pocket digital conductometer
, model CD840).
The conductivity measurement was performed with Jenway 4510 digital conductometer
using a dip-type cell of constant 0.
The pH of spray liquids were measured using Elmetron pH conductometer
CPC-505 equipped with EPS-1 electrode.
The pH was measured with pH meter (Elico LI-120), electrical conductivity was measured with conductometer
(Elico Nitrite, Phosphate and Sulphates were estimated using colorimeter (Elico LI-120).
1997), by measuring an aqueous 20% honey solution at 20[degrees]C, using a conductometer
T70 (Mettler Toledo, Switzerland).
Molar conductance of the Schiff base transition metal complexes was determined in DMSO at room temperature by using Wescan-212 conductometer
Then the content was expressed in mg/100g; electrical conductivity was measured at 20[degrees]C in a 20% (w/v) honey solution in water with a KIT consort conductometer
(CONSORT nv, Belgium) and expressed as |iS/cm, free acidity, lactone acidity, total acidity was determined by automatic titration (TitroLine Easy Schott, Germany).
