“…Analizi istenen ve eser düzeyde bulunan türlerin karmaşık bir matriks içinde bulunuyor olması ve olası girişim etkileri analitik metodlar için sınırlayıcı bir durumdur. Ayırma -zenginleştirme yöntemleri, hem analit derişiminin arttırılmasına olanak sağlar, hem de girişim etkilerini en aza indirmesiyle daha duyarlı analizler yapılabilmesine zemin hazırlar (21). Birlikte çöktürme, sıvı sıvı ekstraksiyon ve katı faz ekstraksiyonu (4-6) gibi zenginleştirme yöntemleri analiz öncesinde numuneye uygulanarak girişim etkileri en aza indirilmeye çalışılır.…”

“…Ayrıca organik çözücü sarfiyatının en az düzeyde tutulması ve birçok farklı teknikle beraber kullanımına olanak sağlaması yöntemin diğer avantajları arasında sayılabilir (22). SPE de kullanılan katı faz adsorban materyali seçimi çeşitlilik göstermekle beraber sentetik reçine ve türevleri, karbon, bakteri ve alg gibi biyolojik substratların kullanıldığı bilinmektedir (21). Son yıllarda zenginleştirme performanslarını arttırmak amacıyla geleneksel olarak kullanılan katı faz adsorban materyallerine alternatif olabileceği düşünülen yeni materyaller üzerinde durulmaktadır.…”

“…Due to nanometer dimensions of particles, nanomaterials might escape from the cartridges. Moreover, the tendency of nanomaterials' particles to aggregate reduces the real superficial area, produces a back-pressure on the extraction devices and may cause a blockage of cartridges leading to extraction failure [17]. Such problems may be omitted by dispersive solid phase extraction (DSPE).…”

This article describes a new procedure for multielement preconcentration of heavy metal ions, specifically of Cr(III), Co(II), Ni(II), Cu(II), Zn(II) and Pb(II) ions. The method is based on dispersive micro solid-phase extraction (DMSPE) of the metal complexes of 2-(5-bromo-2-pyridylazo)-5-diethylaminophenol (5-Br-PADAP) by graphene oxide nanoparticles prior to energy dispersive Xray fluorescence spectrometric (EDXRF) determination. The effects of pH, amount of graphene oxide, concentration of complexing reagent, sample volume and sorption time were optimized. The influence of commonly encountered other ions was also investigated. Under optimal conditions, the calibration plots cover the 2 to 150 ng mL −1 range for each element. The precision (at a 20 ng mL −1 level for n = 10) is lower than 4.8 %, and the detection limits range is from 0.07 to 0.25 ng mL −1 . The DMSPE-EDXRF procedure was successfully applied to the determination of heavy metal ions in water and spiked water samples with recoveries between 94.4 and 103.5 %.

“…As clean water has become a global challenge for many parts of the world, the remedies are required to be practical and cost-effective for mitigation of multifarious waterborne pollutions [1][2][3][4]. Among various environmental remediation routes, filtrations [5,6], absorptions [7,8], and sedimentation [9][10][11] are considered state-of-the-art approaches for large-scale water purification. While prevalent, their effectiveness was limited to colloids and solid suspensions, leaving a considerable performance gap for chemical and biological contaminants.…”

While simple mixing of the multiple nanostructural components might not necessarily satisfy the multiple functional requirements, this research work showed that such structural complexity demanded both strategic structural design and deliberate fabrication methods. As such, nanosilver-hybridized WO 3 nanofibers incorporating paramagnetic CoFe 2 O 4 nanoparticles were for the first time fabricated following three aspects of morphological control-bulk crystallinity, fiber chemical compositions, and surface modifications. Experimentally, co-precipitation, eletrospinning, and photodeposition were employed to synthesize CoFe 2 O 4 nanoparticles, generate magnetically recoverable solar light-active photocatalyst nanofibers, and decorate them with nanosilver, respectively. The successful synthetic steps represented a facile and scalable route to multifunctional nanocatalyst against waterborne pollutants with organic and microbial constituents via WO 3 photocatalytic system. The work extended to nanofiber fabrication using the NS LAB 500 Nanospider machine which allowed for the pilot-scale hybrid nanofibrous catalyst effective under natural sunlight towards elimination of a model waterborne pollutant.
