“…Many phenols are hazardous contaminants because of their toxicity to the environment and living beings [2,3]. Ingestion of water contaminated with high phenol content can cause serious gastrointestinal damage, muscle tremors, difficulty in walking, and death in animals [1,3]. Therefore, Environmental Protection Agency (EPA) regulations try to lower the phenol content in wastewater to below 1 lg mL -1 [4].…”

Activated carbon (AC) was prepared from sapelli wood sawdust using a microwave heating process. The biomass was mixed with inorganic components (lime ? ZnCl 2 and FeCl 3) to form a homogeneous paste. The AC samples are denoted as AC-1A (100 g sapelli wood sawdust ? 20 g lime ? 80 g ZnCl 2), AC-2A (150 g sapelli wood sawdust ? 20 g lime ? 80 g ZnCl 2), AC-1B (100 g sapelli wood sawdust ? 20 g lime ? 40 g ZnCl 2 ? 40 g FeCl 3), and AC-2B (150 g sapelli wood sawdust ? 20 g lime ? 40 g ZnCl 2 ? 40 g FeCl 3). The samples were placed in a microwave oven and pyrolyzed under nitrogen flow. To increase their porosity, the pyrolyzed samples were subjected to a leaching process (with 6 mol L-1 HCl) under reflux to eliminate inorganic components. Several analytical techniques such as Fourier-transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), and N 2 isotherm and vapor adsorption analyses were performed to characterize the AC materials. The samples presented high Brunauer-Electronic supplementary material The online version of this article (

S on yıllarda, canlılar ve halk sağlığı için önemli bir tehdit oluşturan fenol ve bileşiklerinin tespit edilmesi önem kazanmaktadır. Bu çalışmada, fenolün tespiti için moleküler baskılama yöntemi temel alınarak fenol baskılanmış yüzey plazmon rezonans (SPR) sensörler tasarlanmıştır. Fenol moleküllerine ait boşluklara sahip polimerik film hazırlanarak UV polimerizasyonu ile SPR sensör yüzeyinde oluşturulmuştur. 0.15 ile 10 nM arasındaki tayin aralığında en düşük saptama sınırı 0.022 nM'dir. Ayrıca, seçicilik katekolün yarışmacı ajan olarak seçilmiş ve seçicilik deneylerini gerçekleştirilmiştir. Genel olarak, moleküler baskılama yaklaşımı ile hazırlanan fenol baskılanmış SPR sensörünün fenol için oldukça hassas ve seçici olduğu bulunmuştur. Fenol baskılı SPR sensörleri, yüksek seçicilikleri, tekrar kullanılabilirliliği ve hızlı yanıtları özelliği ile mevcut fenol belirleme yöntemlerine alternatif yeni bir yöntem olarak kullanılmak düşünülmektedir.

Activated carbons (ACs) prepared from tucumã seed (Astrocaryum aculeatum) were used for 2-nitrophenol removal from aqueous solutions. The ACs were characterized by elemental analysis, FTIR, N adsorption/desorption isotherms, TGA, hydrophobicity/hydrophilicity balance, and total of acidic and basic groups. The ACs showed to have hydrophilic surfaces and they presented high specific surface areas (up to 1318 m g). In batch optimization studies, maximum removal was obtained at pH 7, contact time of 30 min, adsorbent dosage 1.5 gL and temperature of 50°C. The general-order kinetic model and Liu isotherm model best fit the kinetic and equilibrium adsorption data with a maximum adsorption capacity of 1382 mg g at 50°C. Effect of temperature and thermodynamic studies revealed that the adsorption processes of 2-nitrophenol onto ACs are dependent on temperature and are exothermic and spontaneous, respectively. About the applicability of the ACs for treating simulated effluents, the tucumã seed-activated carbon showed an excellent outcome in the treatment of simulated effluents, evidencing its high efficiency for phenolic compound adsorption. Tucumã seed-ACs showed to be cost effective and highly efficient adsorbents for efficient removal of 2-nitrophenol from aqueous solutions.
