Bu çalışmada, humik
asit sodyum humat çözeltisinden polimer içerikli membranlar (PIMs) kullanılarak
ekstrakte edilmektedir. Sodyum humat, Kahramanmaraş Afşin Elbistan Bölgesindeki
linyitlerden elde edilmiştir. PIMs; polimer selüloz triasetat, taşıyıcı
trikaprilmetilamonyum klorür, modifiyer tributil fosfat ve
plastikleştirici  2- nitrofenil pentil
eter kullanılarak hazırlanmıştır. Polimerik film 2 cam hücre arasına
yerleştirilmiştir. Sıyırma çözeltisi tipi, sıyırma çözeltisi konsantrasyonu,
besleme ve sıyırma çözeltisi karıştırma hızı parametrelerinin ekstraksiyona
etkisi deneysel olarak incelenmiştir. Sıyırma fazına yaklaşık %25 humik asit
geçirilmiş ve UV-Vis spektrofotometresiyle 
ölçülmüştür.

Extraction of humic acid from an aqueous solution with polymer inclusion membranes

Öz

In this study,
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.
