Abstract
Pharmaceutical products and their degradation byproducts are being recently detected in the aquatic environment as emerging contaminants or micropollutants that may affectliving organisms. Their presence at low concentrationsis considered as a challenge for both wastewater treatment process and for analysis or detection procedure.
So this thesis is aiming to monitor of some chemical and pharmaceutical residues in the effluents of pharmaceutical industries such as (caffeine, paracetamol , dexamethasone and naproxen). The identification and quantification of chemical and pharmaceutical residues was investigated using GC/MS spectrometer and liquid chromatographybased tandem mass spectrometry LC/MS/MS spectrometer with electrospray ionization (ESI) .
The most important aim of this study is applying some of advanced water treatment techniques like differen types of activated sawdust to remove these pollutants from water.
Naproxen was selected (nonsteroidal anti-inflammtory drug) to study it’s treatment due to when Naproxen exposed to sunlight it’s converted into two related compounds these photodegradants are predicted to be more toxic than naproxen because they have lower polarity .
To achieve the objectives of this study, the following work was carried out:
1-monitoring forsome chemical and pharmaceutical residues by(EPA 625)using GC/MS/MS & Quantitative analysis is performed by using LC/MS/MS by (EPA 1694)Samples collected from the effluents (before treatment) of a pharmaceutical and chemical Industries facility .
Summary
2-Removal of Naproxen using adsorption by granular activated carbon (GAC) and activated sawdust (SD) and study the effect of doses of activated sawdust , contact time and pH and Temperature conditions to achieve the optimum conditions for naproxen removal
The results showed that qualitative analysis of wastewater recordedpresence of many organic wastewater contaminants with different concentrations and Quantitative analysis of selected four compounds of organic wastewater contaminants reported the presence of dexamethasone in wastewater were detected at 254 ng/mL, for paracetamol at 7325 ng/mL , for caffeine at 9356 ng/mL and for naproxen at 2000 ng/mL . These concentrations representing about 500 fold higher than international safety margins .
Application of advanced water treatment techniques likeadsorbtion on GAC and H2SO4 activated sawdust to remove naproxen from water show the following results:
Removal of Naproxen by H2SO4 activated sawdust showed that as doses of SD H2SO4, and Contact time increases Naproxen removal increases and The optimum conditions for naproxen removal is 0.2g of SD H2SO4,pH2 and Temp. 25oC after 2hours contact time and
The kinetic calculations in the study showed that all removal reactions were second order reaction and the suitable adsorption isotherm equation for naproxen were Langmuirequation and removal of Naproxen by GAC showed that as Contact time increases naproxen removal increases and The optimum conditions for naproxen removal is 0.2g of GAC ,pH2 and Temp. 25oC after 2 hours contact time and
The kinetic calculations in the study showed that all removal reactions were second order reaction and the suitable adsorption isotherm equation for naproxen wereLangmuir equation.
