Phenolic compounds used in food industries and pesticide industry, are environmentally toxic and pollute the rivers and ground water. For that reason, detection of phenolic compounds such as catechol by using simple, efficient and cost‐effective devices have been becoming increasingly popular. In this study, a suitable and a novel matrix was composed using a novel conjugated polymer, namely poly[1‐(5‐(4,8‐bis(5‐(2‐ethylhexyl)thiophen‐2‐yl)benzo[1,2‐b:4,5‐b']dithiophen‐2‐yl)furan‐2‐yl)‐5‐(2‐ethylhexyl)‐3‐(furan‐2‐yl)‐4H thieno[3,4‐c]pyrrole‐4,6(5H)‐dione] (PFTBDT) and carbon dots (CDs) to detect catechol. PFTBDT and CDs were synthesized and the optoelectronic properties of PFTBDT were investigated via electrochemical and spectroelectrochemical studies. Laccase enzyme was immobilized onto the constructed film matrix on the graphite electrode. The proposed biosensor was found to have a low detection limit (1.23 μM) and a high sensitivity (737.44 μA/mM.cm−2) with a linear range of 1.25–175 μM. Finally, the applicability of the proposed enzymatic biosensor was evaluated in a tap water sample and a satisfactory recovery (96–104%) was obtained for catechol determination.

Use of conductive polymer-supported oxide-based photocatalysts for efficient VOCs & SVOCs removal in gas/liquid phase
Ajmal, Zeeshan; Naciri, Yassine; Ahmad, Munir; Hsini, Abdelghani; Bouzıanı, Asmae; Laabd, Mohmed; Raza, Waseem; Murtaza, Adil; Kumar, Anuj; Ullah, Sami; Al-Sehemi, Abdullah G.; Al-Ghamdi, Ahmed A.; Qadeer, Abdul; Hayat, Asif; Djellabi, Ridha (2023-02-01)
Volatile and semi volatile organic compounds (VOCs and SVOCs) are regarding as serious environmental pollutants owign to causing a lot of diseases around the world. The VOCs and SVOCs can be accumulated in both indoor and outdoor areas. Photocatalytic technology has been applied over the last decades in order to purify air and water under solar or artificial lights. To overcome the issues of classical TiO2 photocatalysis, the scientific community has done a lot of research on the engineering of photocatalyt...
Preparation of antimicrobial films from agricultural biomass
Seber, Ayşe Gizem; Bakır, Ufuk; Department of Biotechnology (2010)
Mainly used food packaging materials are petro-chemical based polymers which present environmental problems since they are not biodegradable and ecologically sustainable. In this study, biodegradable biofilms are produced from xylan, extracted from cotton stalk which is an agricultural biowaste without nutritional value. Antimicrobial property was given to the biofilms with either titanium dioxide sol-gel coatings or titanium dioxide powder addition into the biofilm forming solutions. The antimicrobial acti...
Development of fluorescent whole-cell bacterial bioreporters for detection of inorganic arsenic and cadmium
Elçin, Evrim; Öktem, Hüseyin Avni; Department of Biotechnology (2019)
Environmental heavy metal contamination in many regions of the world is a serious problem of ecological health. Fast and constant monitoring of their levels is significant for both preventing their accumulation and taking an immediate action for removal. As an alternative approach to standard laboratory techniques, various biosensor systems for detection of heavy metals have been proposed. Bacterial biosensors hold great promise for in-field detection of heavy metals. In this study, two different whole cell...
Production and characterization of activated carbon from pistachio-nut shell
Özsin, Gamzenur; Yücel, Hayrettin; Behlülgil, Ahmet Kemal; Department of Chemical Engineering (2011)
In this study production and characterization of activated carbon from an agricultural waste, pistachio-nut shells, was investigated. To determine optimum production conditions by chemical activation method, effect of tempreature (300, 500, 700 and 900 oC) and effect of impregnation ratio (1:1, 2:1 and 3:1 as activation agent:sample) were investigated by applying two different methods (raw material activation and char activation) and with two different activation agents (phosphoric acid and potassium hydrox...
Modelling of nitrogen removal in Ankara wastewater treatment plant
Kim, Eun-Ah; Gökçay, Celal F.; Department of Environmental Engineering (2002)
Nowadays environmental legislations in many countries have all imposed strict effluent quality standards for carbon, nitrogen and phosphorous for wastewater treatment plants. This in turn caused complicated design, operation and control of biological treatment systems. As a result, computer programs based on complex mathematical models are now developed for the simulation of such complicated systems. The influent wastewater characterization based on COD and Nitrogen fractionation became very important in de...
