desorption column for dolomite high speed in vietnam prepared using high speed stirrer and stirred for 10 minutes at 500 rpm A homogenous suspension was later obtained b y treating the mixture in ultrasonic apparatus for 1hour prior
Thus static desorption for a preset amount of time is often used followed by a brief dynamic desorption step in order to sweep the desorbed analytes onto the analytical column. In static desorption the interface is filled with a certain amount of solvent and the fibre is allowed to sit in this solvent for a predetermined amount of time.
However NaOH was not further used since the increase in pH values could be a disadvantage regarding the possibility of disposing the dolomite as a soil quality improver. A significant increase in the percentage of phosphate desorption was observed with higher NH 4 Cl concentrations as shown in Fig. 3 .
