“…However, in comparison with other metallic oxides used in extraction procedures for trace elements, it is considered less frequently used one. Yet, it has been successfully applied for the pre-concentration of Ti(IV) in water samples by Zheng et al ( 2009 ) in a batch extraction procedure. Zirconium dioxide was in the form of ultrafine amorphous spherical powder prepared by precipitation in micro-droplets which act as nanoreactors in the microemulsion system composed of cyclohexane/water/TritonX-100/hexyl alcohol.…”

It is indisputable that separation techniques have found their rightful place in current analytical chemistry, considering the growing complexity of analyzed samples and (ultra)trace concentration levels of many studied analytes. Among separation techniques, extraction is one of the most popular ones due to its efficiency, simplicity, low cost and short processing times. Nonetheless, research interests are directed toward the enhancement of performance of these procedures in terms of selectivity. Dispersive solid phase extraction (DSPE) represents a novel alternative to conventional solid phase extraction (SPE) which not only delivers environment-friendly extraction with less solvent consumption, but also significantly improves analytical figures of merit. A miniaturized modification of DSPE, known as dispersive micro-solid phase extraction (DMSPE), is one of the most recent trends and can be applied for the extraction of wide variety of analytes from various liquid matrices. While DSPE procedures generally use sorbents of different origin and sizes, in DMSPE predominantly nanostructured materials are required. The aim of this paper is to provide an overview of recently published original papers on DMSPE procedures in which metallic nanoparticles and hybrid materials containing metallic particles along with other (often carbon-based) constituent(s) at the nanometer level have been utilized for separation and pre-concentration of (ultra)trace elements in liquid samples. The studies included in this review emphasize the great analytical potential of procedures producing reliable results in the analysis of complex liquid matrices, where the detection of target analyte is often complicated by the presence of interfering substances.

The objectives of this study were to assess the suitability of metal oxide nanomaterials for removal of major cations Na+, K+, Ca2+ and Mg2+ from seawater. The as-synthesised nanomaterials were characterized using different techniques, such as XRD, TEM, and BET. The simultaneous removal of Na+, K+, Ca2+ and Mg2+ ion from aqueous solutions by α-Fe2O3 and SiO2/Nb2O5/Fe2O3 nanostructures was studied using batch method. The influence of different experimental parameters (such as initial metal ion concentrations, mass of adsorbent, sample pH and contact time) that affect the simultaneous removal of metal ions was studied using response surface methodology (RSM) based on small central composite design (SCCD). Under optimised conditions, the highest percentage removal was 75%, 92%, 93% and 85% for Na+, K+, Ca2+ and Mg2+, respectively.

“…Various analytical techniques, including neutron activation analysis (NAA) [12], graphite furnace atomic absorption spectrometry (GFAAS) [13], inductively coupled plasma-atomic emission spectrometry (ICP-AES) [14], inductively coupled plasma-mass spectrometry (ICP-MS) [15], X-ray fluorescence (XRF) [16], catalytic adsorptive stripping voltammetry (CASV) [17] and X. F. Du ET AL. 150 spectrophotometry [18][19][20][21][22][23], were used for the determination of Ti (IV) in different types of matrices. Although NAA, GFAAS, ICP-AES, ICP-MS and XRF can determine simultaneously major & trace elements and the combination is considered to have several advantages over the separate technique, spectrophotometry continues to offer the best alternative for routine analysis of Ti (IV) in the absence of these expensive instruments, due to its common availability, simple procedure, high accuracy and low cost effectiveness.…”

“…During the spectrophotometric determination of Ti (IV), a number of organic chromogenic reagents, such as o-carboxyphenylfluorone [19], ponceau S [18], diantipyrylmethane [20], resacetophenone p-hydroxybenzoylhydrazone [24], thiocyanate [25], 2,3-dihydroxynaphthalene [26], 3,5,7,2',4'-penta hydroxy flavone [27], 5-(2', 4'-dimethylphenylazo)-6-hydroxypyrimidine-2,4-dione [28], bromopyrogallol red [29] and o-chlorophenylfluorone [30], have been used to produce an intense color for absorbance measurement. Most of these reagents are expensive, harder-to-obtain and environmental-unfriendly.…”

Introduction of titanium oxides with high permittivity on etched aluminum foils' surface has been successfully utilized to increase specific capacitance of anode foils for aluminum electrolytic capacitors. In order to quantify the concentration of titanium (IV) on the etched aluminum foil precisely, a simple and rapid spectrophotometric procedure has been developed. After optimizing a series of variables including absorbance wavelength, concentration of nitric acid, concentration of hydrogen peroxide, nitration time and developing time, analytical precision and accuracy were tested by using standard working solution containing known amount of titanium (IV). The results showed that Lambert-Beer's law was obeyed in the range of 0.01 to 3.00 mmol•L −1. The relative standard deviation (RSD) ranged from 0.67% to 1.09% (n = 6), and the recovery was between 99.17%-100.03%. Investigation on effect of Al 3+ ion indicated that there was no interference in the absorbance of titanium (IV) at 410 nm. The proposed procedure was applied to real samples for the determination of titanium (IV), and the results were in a good agreement with the values certified by inductively coupled plasma-atomic emission spectrometry (ICP-AES).
