A simple method has been developed for the preconcentration of mercury based on the adsorption of its Schiff’s base diphenylthiocarbazone (DPC)complex on a silica gel-immobilized Schiff’s base diphenylthiocarbazone (DPC)column. The influence of acidity, eluting agents, stability of the column, sample volume and interfering ions has been investigated in detail. The adsorbed complex could be elut...

Cannabinoids, in contrast to typical drugs of abuse, have been shown to exert complex effects on behavioural reinforcement and psychomotor function. We have shown that cannabinoid agonists lack reinforcing/rewarding properties in the intracranial self-stimulation (ICSS) paradigm and that the CB1 receptor (CB1R) agonist WIN55,212-2 attenuates the reward-facilitating actions of cocaine. We sought...
