| Abstract: | A laboratory study was conducted to remove and
recover lead from aqueous solution using supported liquid membrane (SLM)
process. Preliminary solvent extraction studies, on lead revealed the iodo
system with tributyl phosphate (TBP) as liquid membrane and sodium hydroxide as
strippant to be an efficient one. Using synthetic lead(II) solution, the
process parameters like feed side pH, strippant concentration, KI concentration
and stirring speed were optimized. The initial lead concentration of 25 mg/L gave
satisfactory result with complete removal and recovery in 4 h of operation with
a permeability coefficient of 1.146 × 10-5 m/s. |
