Abstract The significant problem is the treatment of landfill leachate characterized by high chemical oxygen demand (COD) and total organic carbon (TOC) presence biodegradation inhibitors such as heavy metals oily substances. For case (pH 7.9, color 1550 mg Pt/L, COD 1880 O 2 /L, TOC 620 mg/L, nitrogen (TN) 220 phosphorus (TP) 6 mg/L metals), effect elevated pressure temperature on decrease val...

The use of ferrate has been demonstrated as a highly efficient technique for the removal pollutants in water and wastewater treatment. While most published work about investigated treatment performance by alone, new applications expand to synergistic application with other techniques such membrane separation, sulphur-based chemical use, UV radiation, ozonation, acidification, additives. This pa...

The effects of sonication, potassium ferrate (K2FeO4) oxidation and their simultaneous combination (called “sono-oxidative pre-treatment”) on chemical properties and anaerobic digestion of waste activated sludge (WAS) were investigated and compared comprehensively. Based on chemical parameters, the optimum operating conditions were found to be 0.3 g K2FeO4/g total solids (TS) dosage for 2-h ind...

The goal of this experiment is to evaluate the effectiveness of different leachate pre-treatment options in terms of COD and ammonia removal. This research focused on the evaluation of physical-chemical methods for pre-treatment of leachate that would be effective and rapid in order to satisfy the requirements of the sewer discharge by-laws. The four pre-treatment options evaluated were: air st...

Doxycycline (DOX), a typical antibiotic, is harmful to aquatic ecosystems and human health. This study presents DOX removal by potassium ferrate (Fe(VI)) montmorillonite investigates the effect of Fe(VI) dosage, reaction time, initial pH value, adsorption pH, time temperature on removal. The results show that increases when increasing with optimal condition for (~97%) observed under molar ratio...

A novel, versatile route to phosphorus- and carbon-substituted η(5)-phosphacyclohexadienyl complexes was developed. Reaction of the anionic 2,4,6-triphenylphosphinine iron complex [K([18]crown-6)(thf)2][Cp*Fe(PC5Ph3H2)] (1) with selected main group element electrophiles afforded the new complexes [Cp*Fe(2-endo-H-PC5Ph3H2)] (endo-3), [Cp*Fe(2-exo-H-PC5Ph3H2)] (exo-3), [Cp*Fe(1-Me-PC5Ph3H2)] (4),...
