Abstract

Adsorption lead (II) ion onto three different surfa ctant, anionic as a Sodium dodecyl sulfate (SDS), c ationic Cetayl trimethyl ammonium bromide(CTAB) and nonionic Trito n X-100. under different experimental conditions we re studied. From aqueous solutions and has been invest igated through batch mode adsorption experimental. And have been studied adsorption at different PH (4-9) deter mine by using HANNA,PH-Meter(Instrument, Portugal. Electronic Balance Sartorius, W. Germany). and ef fect temperature change from (293 to 328) K ͦ . Kinetic study shown this adsorption followed pseudo first order. The experimental isotherm data were analyzed by usi ng two isotherm models the Langmuir and Freundlich equati ons. Our results provide that the adsorption proces s was spontaneous and exothermic under natural conditions . All the data were carried out by (UV- Visible Spectrophotometer(Libra Biochrom S60, England) afte r and before add surfactants.
