After the optimum volume and pH of the sample were determined, the effect of the concentration of the compounds and matrix were investigated. The highest recovery rates for antibiotic compounds were determined between 82% and 105% in 200 mL sample volume and pH 2.5. Then, antibiotic compounds were investigated in influent and effluent samples taken from Konya Urban Wastewater Treatment Plant. The concentration of the antibiotics was detected range of 0.11-101 ng/L in influent waters andeninfo:eu-repo/semantics/closedAccessAntibioticLc-Ms/MsRisk AssessmentSpeWastewaterArticle73201212WOS:00047587150000310.12989/aer.2018.7.3.201
