“…The selectivity of this procedure is examined to detect the interference of coexisting ions. Metal ions such as ions Zn(II), Fe(III), Fe(II), Sn(II), Ni(II), Ca(II), Al(III), Sr(II), Cu(II), Mn(II), Co(II), Mg(II), Ag(I) and Pb(II) challenge this detection technique [27]. Each type of metal ion has a concentration of 500 ppb.…”

Citrate-capped gold nanoparticle (GNP) was used as a ligand for chromium chelating, and chromium ions reaction led to GNP aggregation. The color change of GNP by aggregation in the presence of chromium is a simple and rapid colorimetric test for these ions in an aqueous solution. GNP capped citrate was prepared by the citrate method and characterized by TEM, and its particle size was 20 nm. Also, the surface plasmon resonance (SPR) peak was 520 nm. In the presence of chromium ions, the color of GNP at 520 nm was shifted to 650 nm because of aggregation to give a signal as a ratio of A650/520 more than one and proportional with chromium concentration directly. The optimum conditions were studied to obtain the high signal represented by the volume of GNP, reaction kinetic of A650 with time, selectivity, and interferences of Zn(II), Fe(III), Fe(II), Sn(II), Ni(II), Ca(II), Al(III), Sr(II), Cu(II), Mn(II), Co(II), Mg(II), Ag(I), and Pb(II) ions. The calibration curve is linear in the range of 100–500 ppb, and the regression was 0.9951 and applied on tap water chromium ions in the same range in the regression of 0.95. This method was simple, rapid reaction, consumed low volumes of sample, and had low detection limits. It can be recommended as a new method for chromium (III) detection in aqueous solutions.

“…Currently, new, robust, sensitive, selective, inexpensive, and fast optical [24][25][26], chemical [27,28], and biological [29][30][31][32][33] sensory systems are currently in status of development. Such advances in analytical chemistry are currently tightly connected to nanotechnology [26,28,34]. Moreover, so-called lab-on-paper sensors were also developed for heavy metal determination, as demonstrated for quantification of mercury, silver, copper, cadmium, lead, chromium, and nickel [29].…”

“…In this context, a disposable colorimetric sensor which include a combination of a host strip and a spectroscopic probe, are more promising, require less labor and low‐cost instrumentation compared to closely relate fluorescent systems. Colorimetric sensors have recently attracted great attention in recognition of various hazardous materials and gases because of their capability for naked‐eye visual recognition, simplicity, high sensitivity, rapidity, and cheapness as well as the fact that there is no requirement for any sophisticated instruments …”

[21][22][23][24][25][26][27][28][29][30][31][32] Recently, the polyphenolic biomolecule, tannic acid (TA), has attracted interest due to its antimicrobial and antioxidant properties. The molecular structure of tannic acid is displayed in Figure 1.…”

Selective Colorimetric Detection of Fe (III) Using Metallochromic Tannin‐Impregnated Silica Strips

A solid state sensor tool used for determination of ferric ions (Fe+3) in an aqueous medium was developed using the environmental friendly tannin polyphenolic biomolecule as spectroscopic probe and silica plates as a host strip. The colorimetric recognition of the analyte is based on a tanna‐activated silica dipstick with a determination limit in the ppm level. The best detection of Fe (III) was accomplished in a pH range from 3.2 to 8.8. The metallochromic tannin‐impregnated silica diagnostic tool provided an instant color alteration from yellow to dark purple upon immersion in an aqueous environment of ferric cation as was demonstrated by the coloration measurements. This color shift is proportionally correlated with increasing the ferric concentration. Both qualitative and quantitative studies were performed. The sensor demonstrated high selectivity to Fe (III), while no color change was monitored for other metals. The recognition mechanism of ferric occurs via tannic (polyphenolic)‐Fe (III) polydentate complex creation. Different spectroscopic techniques, including scanning electron microscope, energy dispersive X‐ray spectroscopy as well as elemental mapping were utilized to characterize the tannic‐Fe (III) complex formation on the silica dipstick.
