“…Therefore, Ni 2+ presence in water is necessary to be detected. The detection of Ni 2+ is developed through many techniques using several instruments, such as inductively coupled plasma optical emission spectrometry (ICP-OES) [1], atomic absorption spectrometry (AAS) [2], and UV-vis spectroscopy [3]. However, these methods are expensive, time-consuming, and require trained personnel.…”

A rapid and selective colorimetric detection of Ni2+ was developed using silver nanoparticles (AgNPs) with β-cyclodextrin (β-CDs) as reducing and stabilizing agents. Characterization was assessed by spectrophotometer UV-vis, Fourier transform infra-red (FTIR), transmission electron microscopy (TEM), and particle size analyzer (PSA). The AgNPs-β-CDs were relatively stable after being stored for 5 months. The addition of Ni2+ to the AgNPs-β-CDs shifted the surface plasmon resonance (SPR) band at 409 nm. Synthesized AgNPs-β-CDs had a spherical shape and an average size of 25.07 ± 0.66 nm (analyzed by TEM) and 33.63 ± 0.25 nm, as confirmed by PSA. AgNPs-β-CDs as colorimetric sensors for Ni2+ ions had a good linear calibration curve at 409 nm with the R2 value of 0.9993. The limit of detection (LoD) was found to be 33.30 ppb, while the limit of quantification (LoQ) was 111.0 ppb. This sensor had been applied to a seawater sample from Ancol Beach, North Jakarta, Indonesia and it exhibited good precision and accuracy. In this work, β-CDs-synthesized AgNPs were able to detect Ni2+ ions and were beneficial as an alternative method for Ni2+ screening in environmental samples.

“…8 Thus, it is paramount to be able to accurately detect the concentration of Cd 2+ in drinking water and fresh water to defend the environment and evade pollution. Traditional methods of Cd 2+ detection focus on inductively coupled plasma atomic emission spectrometry, 9 atomic absorption/fluorescence spectrometry, 10 cold vapor atomic fluorescence spectrometry, 11 fluorescence spectroscopy, 12,13 and electrochemical approaches. 14,15 Among these, the electrochemical method has attracted research attention due to its merits, such as simplicity, cost-effectiveness, and high sensitivity.…”

A Novel Fluorescent 1,10‐Phenanthroline‐2,9‐dicarboxaldehyde‐ 2,5‐diaminoterephthalicacid‐Schiff Base Polymer for Cu²⁺ Detection

A novel fluorescent Schiff base polymer (PTDA-DATA-SBP) is synthesized by amine aldehyde condensation reaction between 1,10-phenanthroline-2,9-dicarboxaldehyde (PTDA) and 2,5-diaminoterephthalicacid (DATA) as a selective fluorescent probe for Cu 2 + detection. The as-prepared PTDA-DATA-SBP displayed irregular nanospheres with a diameter of about 5 μm. Under the excitation of 338 nm, the PTDA-DATA-SBP had a characteristic emission peak at 565 nm. The PTDA groups in PTDA-DATA-SBP could coordinate with Cu 2 + under help of carboxyl groups of DATA. Owing to the photoinduced electron transfer mechanism, the fluorescence of PTDA-DATA-SBP was weak-ened after the addition of Cu 2 + in the presence of common ions. Hence, the PTDA-DATA-SBP was exploited as a fluorescent nanosensor for sensing Cu 2 + . The PTDA-DATA-SBP showed high selectivity and fast response towards Cu 2 + even in presence of other relevant metal ions. The PTDA-DATA-SBP fluorescent sensor has a good linear range of 3.45 nM-8.00 μM, and the limit of detection was as low as 1.15 nM. The proposed PTDA-DATA-SBP sensor could also detect Cu 2 + in actual samples. The work not only provided a good fluorescent probe for Cu 2 + detection but also provided a feasible strategy to construct highly selective fluorescent probes.
