“…The processes which have been proposed as mainly responsible for this reduction are sorption and biodegradation. The determination of the contribution of each in the removal process, however, has rarely been investigated (García-Jares et al 2002). The most common assumption is that detected pharmaceuticals in WWTPs would be removed mainly through biodegradation and not sorption; hence, sorption process has rarely been investigated.…”

The main objective of this study was to evaluate the contribution of sorption to the removal of two commonly used antibiotics (amoxicillin and ciprofloxacin) from wastewater. These antibiotics are excreted in large quantities with more than 75% of them being unmetabolized and are therefore likely to end up in domestic wastewater in significant quantities. The specific objectives were to determine the sorption behavior in synthetic wastewater (SWW), the effect of pH and contribution of microbial surfaces, to the sorption of these antibiotics. The SWW, adjusted to various pH levels, was used and sorption kinetics conducted at 100 and 250 μg L −1 concentrations. Adsorption isotherms were determined at different pH levels. The SWW (pH 6.6) was inoculated with Rhodococcus sp. B30 strain to determine the contribution of microbial surfaces to sorption. Generally, both antibiotics revealed a decrease in sorption with pH increase, suggesting that lowering the solution pH of the wastewater may reduce their amounts in wastewater solution. Comparatively, ciprofloxacin exhibited higher sorption than amoxicillin. The sorption distribution coefficient (K d ) values for ciprofloxacin ranged from 0.4356 to 0.8902 Lg −1 , with pH=5.5 exhibiting the highest K d , while that for amoxicillin ranged from 0.1582 to 0.3858 Lg −1 with the highest K d at pH=3.5. There was a significant difference (p<0.05) in K d values between various pH levels for both antibiotics except between the pH of 5.5 and 6.6. Both antibiotics were not degraded within 48 h by Rhodococcus sp. B30 strain. These results indicate that degradation may not be the major process of removal of compounds from wastewater treatment plants and hence the importance of sorption as an intervention technique.

“…In general, for the most volatile compounds (1-27) PDMS-DVB and CAR-PDMS fibers achieved the best yields, and PDMS fiber gave the lowest extraction efficiencies. In the case of the least volatile pyrethroids (28)(29)(30)(31)(32)(33)(34)(35), close responses were in general obtained with PDMS, PDMS-DVB, CAR-PDMS and PA fibers, while CW-DVB fiber was the least …”

“…However, Basaglia and Pietrogrande [60] preferred to use a PA fiber, justifying their choice in that PA has better resistance than PDMS for on-fiber derivatization with BSTFA. However, García-Jares et al observed better performance with (HS)SPME than with (DI)SPME for the extraction of polycyclic [85] and nitro musks [86], respectively, by using either CAR-PDMS or PDMS-DVB fibers. Wang et al [88] used (HS)SPME for extracting polycyclic musk, using a PDMS-DVB fiber based on the findings of García-Jares et al [85], and studied the influence of heating the sample by microwave radiation during the extraction, which resulted in a substantial decrease of the extraction time.…”

Personal-care products (PCPs) could reach the aquatic environment and cause a great impact in the aquatic ecosystem. In this sense, the monitoring of these emerging pollutants in the environment yields valuable information. For this reason, analytical methods to determine PCPs in environmental waters are needed. Due to the low concentration of the PCPs, i.e. ng L À1 , sensitive methods are needed. This required sensitivity can be achieved by using sensitive analytical techniques during the measurement step, or by employing enrichment techniques during the sample treatment step. Obviously, the combination of both sensitive analytical techniques and extraction techniques considerably improves the quality of the determination.In this way, in the last years, different analytical methods have been developed to determine PCPs in environmental waters from different origin, i.e., water from sea, lake, river, influent and/or effluent wastewater treatment plant, swimming pool, tap, and groundwater. The aim of this chapter is to compile and discuss the analytical literature dealing with the development and validation of analytical methods for determining PCPs in environmental water samples, emphasizing both the employed sample treatment and the subsequent analytical technique.
