“…After 5 s, The SPR chip was removed and polymerization was started by UV light (100 W, 365 nm) for 1 h. Because there is non-covalent interactions between monomer and template molecule, the polymerization of UV light is performed on SPR chip surface. Last, the polymer coated SPR chip was washed with ethanol several times, then dried in vacuum oven [33,34]. The SPR chips were stored in closed box without fluctuations of temperature and pressure.…”

“…In view of these facts, it was considered worthwhile to develop fast, effective, economic and reproducible method for the subtraction of atrazine from water. The literature shows some adsorption methods for the removal of atrazine (Gai et al 2011;Zhang et al 2011;Chaparadza and Hossenlopp 2012;Báez et al 2013;Silva et al 2013;Zhao et al 2013;Yola et al 2014;Gupta et al 2015). It was observed that some methods work at extreme pHs, which are not suitable to work under natural water conditions.…”

Atrazine organic pollutant has been found in several water resources of the world. It is highly toxic and carcinogenic in nature. Atrazine is removed by adsorption on iron composite nanoparticles. The composite nanoparticles were synthesized, analyzed and applied for atrazine uptake from water. Residual atrazine was monitored by gas chromatography-mass spectrometry. The maximum atrazine removal (95 %) was achieved using contact time 30.0 min, concentration 30.0 lg/L, pH 7.0, dose 2.5 g/L and temperature 20.0°C. The adsorbent was selective for atrazine adsorption. The results obeyed Langmuir, Freundlich, Temkin and Dubinin-Radushkevich isotherms. DG°values were -6.05, -6.11 and -6.15 kJ/mol at 20, 25 and 30°C temperatures, respectively. The value of DS°w as -2.45 9 10 -3 kJ/mol K. It showed decline in entropy of atrazine uptake. The adsorption followed pseudo-second-order kinetics. The adsorption mechanism was liquid film diffusion. The proposed adsorption method is inexpensive, fast and reproducible. It can be used to remove atrazine from any water sample/source.

“…QCM sensors have mainly been used for detecting trace compounds in air. In recent decades, advances in QCM methodology have enabled liquid applications and some researchers have used QCM measurements to analyze wastewater samples [19,20]. Yang and Zhang [19] showed the selective detection of Cu 2+ among various metal ions in real wastewater.…”

Abstract:In anaerobic digestion (AD), long-chain fatty acids (LCFAs) produced by hydrolysis of lipids, exhibit toxicity against microorganisms when their concentration exceeds several millimolar. An absorption detection system using a quartz crystal microbalance (QCM) was developed to monitor the LCFA concentration during an anaerobic digester's operation treating oily organic waste. The dissociation of the LCFAs considerably improved the sensor response and, moreover, enabled it to specifically detect LCFA from the mixture of LCFA and triglyceride. Under alkaline conditions, the frequency-shift rates of the QCM sensor linearly increased in accordance with palmitic acid concentration in the range of 0-100 mg/L. Frequency changes caused by anaerobic digestate samples were successfully measured after removing suspended solids and adjusting the pH to 10.7. Finally, the QCM measurements for digestate samples demonstrated that frequency-shift rates are highly correlated with LCFA concentrations, which confirmed that the newly developed QCM sensor is helpful for LCFA monitoring in terms of rapidness and usability.
