Evaluation of carbaryl sorption in alluvial soil
This study investigated the adsorption potential of carbaryl onto alluvial soil. Parameters that influence the adsorption process such as pH, adsorbent dose, initial carbaryl concentration, stirring rate, particle size, contact time and temperature were studied in a batch process.

| description | This study investigated the adsorption potential of carbaryl onto alluvial soil. Parameters that influence the adsorption
process such as pH, adsorbent dose, initial carbaryl concentration, stirring rate, particle size, contact time and temperature
were studied in a batch process. The carbaryl adsorption capacity was at maximum at pH 6 for an initial concentration of 20
ppm. Adsorption equilibirium time was observed in 180 min. Equilibrium adsorption data was best fitted with Freundlich
isotherm and pseudo-first order kinetic model, respectively. The adsorbent was characterized by X-ray diffraction spectrum,
Fourier transform infrared spectroscopy and scanning electron microscopy. The experiment performed indicated that the
adsorption capacity of carbaryl was significantly correlated with particle size, organic matter and pH of the soil. Therefore,
the possibility for carbaryl to contaminate underground water may be greater in the presence of low organic matter content. |
