Preferred Abstract (Original):
Imidaclopid
and abamectin are the most pesticides used in Palestine for
agricultural purpose. Those pesticides released some amount to the soil
and this will affect both soil and groundwater. Results indicate that
the highest percentage of imidacloprid and abamectin removal was 13.4 %
and 7.5 % respectively when adsorbent dosage was 3.0 g. At low pH of1.5
the percentage of imidacloprid removal increases reached to 12.3 %, but
the decrease of imidacloprid removal at high pH of 12 is highly extreme
reached to 7.3 % . At high pH "12" the percentage of abamectin removal
increases reached to14.4 %, but the lowest percentage of abamectin removal at pH 7 reached to 9.1 %. The effect of temperature on adsorptionby
soil has also been investigated in the range of 15–47°C. The
investigation of adsorption behavior of the two pesticides on soil, was
studied using both Langmuir and Freundlich isotherms were used to
explain equilibrium adsorption, from these isotherms it was evaluated
that Langmuir isotherm was obeyed well.
