In this paper, gold nanoparticles (AuPNs) and activated carbon (AC) modified electrode was used for the determination of luteolin. Porous activated carbon was made from coconut shell powder. The electrode was coated by Porous activated carbon, and then gold nanoparticles were electrodeposited on the porous carbon surface. Electrochemical behavior of luteolin was analyzed by gold nanoparticles@ activated carbon modified electrode. The results show that the detection range of luteolin is 1.8 μmol/L to 10 μmol/L (R2 = 0.9863) with the detection limit of 0.1 nmol/L (3σ/slope), and the recommended method has a good recovery for the detection of luteolin in real urine.

This paper describes the hydrophobic effect in the process of adsorption of alkyltrimethylammonium bromides from aqueous solution on to an activated carbon surface. Measurements of the adsorption isotherms of a series of alkyltrimethylammonium bromides with different hydrocarbon tail lengths at the activated carbon surface were carried out. In order to investigate the temperature dependence of the adsorption process, the determination of the adsorption of cetyltrimethylammonium bromide (CTAB) was undertaken at different temperatures in the range 20–60°C. From the experimental results obtained, the relevant thermodynamic quantities have been calculated. The role played by the hydrophobic effect in the adsorption process of cationic surfactants on to activated carbon and the factors affecting the adsorption mechanism were discussed.
