title: [Experimental study on adsorption effect of activated carbon to abamectin].
abstract: OBJECTIVE
  To investigate the adsorbability of activated charcoals for abamectin in vitro at various pH and concentrations.
  
  
  METHODS
  Three concentrations of abamectin solutions (10, 5 and 2.5 g/L) with different pH value ( pH1.9 and pH6.8, respectively) were mixed with activated charcoal and control, respectively. The concentrations of abamectin were measured by UV-visible spectrophotometry after vibrated, incubated and centrifuged on different time points. Calculate the residue rate of abamectin and adsorption rate of activated carbon for avermectins.
  
  
  RESULTS
  The abamectin was significantly decreased in activated charcoal group compared with control group and the absorption ability of activated charcoal was higher on low concentration of abamectin.
  
  
  CONCLUSIONS
  In vitro experiment showed that activated charcoal can significantly adsorb abamectin.
