Abstract

Separation of phenol coumpounds which containing sulphuric and phosphoric ions have been conducted using the modificated liquid mernbrane emultion techniq,r". Tt " modificated membrane phase consist of kerosine and paraffine as organic phase, combination of sorbitan monostearat (span 60) and tween 80 emulgators as surfactant and NaOH solution as internal phase. phenol compounds that have been extracted is determined by spectrophotometre at 510 nm using 4-aminoantipirin methode. The effect of both of ions on the extraction effeciences on plinol conmpound is deteflnined for all treatnents. The results have shown that with out bottr of ions the exfraction effcience on phenol rs 97,12o/o. The precents of sulphuric ions from NazSO+, HzSOq, OIII4)2SO+ and phosphoric ions from Na3Po4, H3POa, OIH4)2PO+ in internal phase give ctranglng of the extraction effciences . A light decriesing of extractiott'"fft"i.rrcens on phenol are not caused of sulphuric or phosporic ion but cations from their salts.
