“…Synthesis of the new organic or inorganic compounds and investigation of their interaction with metal ions [13,14] for sensitive and selective determination of the metal ions is also an efficient solution. [15,16] There are many colorimetric sensors based on rhodamine B due to its high color properties in the literature. These studies were done by using the fluorescent and absorbance characteristic of this dye.…”

Rhodamine B hydrazide and 2-chloroquinoline-3-carbaldehyde derivatives were used to synthesize novel colorimetric sensors for highly selective detection of copper ion. The measurement was based on the interaction between the synthesized ligands and Cu 2 + and the sharp color change of the ligand from yellow to pink in the presence of Cu 2 +. Increase in absorbance intensity at the new appeared absorbance peak was used as an analytical signal. The effect of parameters, such as time and sensor concentration were also investigated and discussed. The calibration curve was considered too under the optimum experimental conditions and was linear in the range 0.05-5.00 μg mL À 1 with a limit of detection 0.016 μg mL À 1. The interferences of some common ions were studied and the synthetic ligand was found to be a high selective sensor. Selectivity of the proposed method makes it as an applicable technique for the determination of copper in foodstuff samples.

“…Among these, the colorimetric chemosensors are inexpensive, and it will detect the presence of an analyte in a small amount sample in which the target moiety is recognized by naked‐eye. On the other hand, colorimetric sensing methods offer numerous advantages in comparison with the other instrumental methods, viz terms of simple synthesis, sensitivity, field monitoring, fast results and they are non‐destructive …”

A Schiff's base colorimetric chemosensors R1–R3 consist of carbohydrazide, and heterocyclic aldehydes have been designed and synthesized for sensing of heavy metal ions. Synthesized receptors were well characterized by various standard spectroscopic techniques. The receptor R1 exhibited multi‐ion selectivity for Cd2+, Hg2+, Pb2+, Cu2+ ions and showed lowest detection limit of 1.9 ppb, for Cd2+ & Hg2+ ions. The receptors R2 and R3 displayed dual ion selectivity (R2 for Hg2+, Cu2+, and R3 for Cu2+, AsO2– ions) in an aqueous medium at ppb levels. The UV–Vis and colorimetric studies confirmed the selectivity and sensitivity of chemosensors R1–R3 in the presence of other interfering metal ions. Further, using the B–H plot, FT‐IR, and mass analysis data, the binding modes, stoichiometric ratios of receptors R1–R3 with the metal ions were investigated. The estimated association constant values were found to be 104 to 105 M–1/M–2. The experimental results are well concordant with that of calculated theoretical DFT results. The receptors R1–R3 exhibited good sensitivity and selectivity compared to literature reports and successfully demonstrated for test strip applications.

“…The household plumbing systems, battery manufacturing, chemical manufacturing, mining, corrosion of pipes, fertilizers, paints, and pigments are the major sources of copper (Tamez et al 2016). The commended daily allowance of copper ranges from 0.4 to 0.6 mg for infants, 1.5 to 2.5 mg for children, and 1.5 to 3.0 mg for adults (Liu et al 2015). USEPA states that the maximum allowable contamination level of copper is 1.3 mg/L in drinking waters (Özlem Kocabaş-Ataklı and Yürüm 2013).…”

A macroporous glycidyl methacrylate (GMA)-methylmethacrylate (MMA)-divinyl benzene ( D V B ) t e r p o l y m e r f u n c t i o n a l i z e d w i t h diethylenetriamine tetraacetic acid (DTTA) (GMA-MMA-DVB-DTTA) sorbent was successfully applied for the uptake of Cu(II) from the aqueous solutions. Adsorption characteristics for copper ion were investigated by a batch sorption in under different experimental conditions, and the optimum parameters for the quantitative sorption of Cu(II) ion were found to be as follows: pH of 7.0, a contact time of 30.0 min, and a sorbent amount/solution volume ratio of 1.5 mg/mL. The quantitative elution from the sorbent was performed with 1.0 M HCl (>95 %). Among three kinetic models, the pseudo-second-order kinetic model provides the best correlation for the process. The nonlinear resolution of the Langmuir isotherm equation has been found to show the closest fit to the equilibrium data. The results indicates that the presence of the competitor ions (Al, Ba, Co, Mn, Mg, and Ni) has no obvious influence on the sorption of Cu(II) ion under the optimum conditions and the polymeric sorbent has a good selectivity for the sorption of Cu(II) ions with a sorption percent of ≥99 %. Sorption/desorption studies were performed for ultrapure, tap, bottled drinking and industrial wastewater samples, and it is examined that the proposed method has been successfully applied to the real samples for the removal of Cu(II) acceptable accuracy and precision. The results of this work indicated that the polymeric sorbent could be a simple and suitable method for the effective removal of Cu(II) ions from waters.
