humic acid was extracted from the solution of sodium humate by using polymer
inclusion membranes (PIMs). Sodium humate was obtained by treating lignite from
Kahramanmaraş Afşin-Elbistan Region. PIMs were prepared by using cellulose
triacetate as polymer, a carrier, tricaprylmethylammonium chloride, modifier
tri-butyl phosphate and plasticizer 2- nitro phenyl pentyl ether. The polymeric
film was placed between two glass cells. The effect of the stripping solution
type, stripping solution concentration and feed and stripping solution mixing
rate parameters were experimentally investigated. About 25% humic acid was
passed to the stripping phase and measured by UV-Vis spectrophotometer. </p> <p> </p>}, number={6}, publisher={Sakarya University}
