Removal of Pb(II) from aqueous solution on chitosan/TiO(2) hybrid film.

This paper presents the adsorption of Pb(II) from aqueous solution using chitosan/TiO(2) hybrid film (CTF) adsorbent. Batch experiments were carried out as a function of solution pH, adsorption time, Pb(II) concentration and temperature. The equilibrium data fitted well with the linear Freundlich model.

Simultaneous determination of omethoate and dichlorvos by capillary electrophoresis.

A capillary electrophoresis method has been developed for the analysis of omethoate and dichlorvos. Response surface methodology (RSM) was used to optimize the separate conditions for simultaneous detection of omethoate and dichlorvos. The results indicated that the optimal conditions for omethoate and dichlorvos determination were; pH 7.
