Abstract

Bazı kimyasalların (Mn3O4, KIO3) ve radikal tutucuların (Na2CO3, t-butil alkol) sonikasyon (SN) ile zeytinaltı atıksuyundan (ZA) giderim verimine etkisi incelendi. Maksimum (mak.) toplam fenol (TF) ve toplam aromatik amin (TAA) giderimleri %88 ve %79, sırasıyla, 60oC yalnızca 150 dakika (d) SN’la bulundu. Mak. fenol giderimi %98 ile 19mg/L perfluorohekzan ile %99 TAA giderimi 16mg/L KIO3’le gözlendi. Katekol, tayrosol, quersetin, kaffeic asit, 4-metil katekol, 2-fenil fenol (2-FF) ve 3-fenil fenol (3-FF) fenol ara ürünleri; trimetilanilin, anilin, otoludin, o-anisidin, dimetilanilin, etilbenzen ve duren (1,2,4,5-tetramethilbenzen) TAA ara ürünleri ZA’da tanımlandı. Mak. akut toksisite giderimleri sırasıyla, %98 Vibrio fischeri ve %97 Daphnia magna’dir. TF, TAA ve toksisitenin ZA’dan SN’la gideriminde etkili ve ekonomiktir

Treatment of Dephenolization, dearomatization and detoxification of olive mill wastewater with sonication

Abstract

The effects of some additives (Mn3O4, KIO3) and some radical scavengers (Na2CO3, t-buthyl alcohol) on the sonication of olive mill effluent wastewater (OMW) were investigated. The maximum (max.) total phenol and total aromatic amines (TAAs) removals were 88 and 79%, respectively, at 60oC with only 150 min sonication. The max. phenol removal was observed as 98% with 19mg/L perfluorohexane with the max. TAAs removal was 99% with 16mg/L KIO3. Cathecol, tyrosol, quercetin, caffeic acid, 4-methyl catechol, 2-phenyl-phenol (2-PHE) and 3-phenyl-phenol (3-PHE) were detected as phenol intermediates while trimetlyaniline, aniline, o-toluidine, oanisidine, dimethylaniline, ethylbenzene and durene [1,2,4,5-tetramethylbenzene] were identified as TAAs intermediates in the OMW. The max. acute toxicity removals were 98% Vibrio fischeri and and 97% Daphnia magna, respectively. Total phenol, TAAs and the toxicity in an OMW were removed efficiently and cost–effectively through sonication
