Objectives: An optical chemical sensor membrane obtained by physical inclusion of a 2-nitro-6-(thiazol-2-yl-diazenyl)phenol (NTDP) as a selectophore and polymethyl methacrylate (PMMA) and 2-nitrophenyl octyl ether (NPOE) as a plasticizer. Methods: The adsorption of Lu(III) causes the colour of the membrane to change from orange to pink with maximum absorbance (λmax) at 606 nm. The sensor membrane gives the best response towards Lu(III) ion at pH 6.5, after 10 min of contact time, at 150 ng mL -1 Lu(III), and 10 mL solution. Results: A linear Lu(III) calibration curve can be developed in the concentration range of 5.0-280 ng mL -1 with R 2 = 0.9990. The molar absorptivity is found to be 9.06 x 10 6 L mol -1 cm -1 . The detection and of quantification limits are found to be 1.63 and 4.95 ng mL -1 , respectively. Conclusion: The optical sensor membrane analytical characteristics was performed as interference of anions and cations, equilibrated time, reusability, detection limit, etc. and compared with the previous different conventional methods for Lu(III) using various chromophores. The optical sensor membrane investigated in this work was examined in real samples with excellent results comparing with the previous ICP-OES method.

“…In order to increase the porosity of the membrane, the triacetyl cellulose film was hydrolyzed to deesterify the acetyl groups. This was accomplished by treating the membrane with 1.0 mol L −1 NaOH solution for 48 h. The film was then washed with distilled water before being used [26].…”

In the present work, a novel optical chemical sensor (optode) was prepared based on impregnation of N, N´-bis (salicylidene)-1, 3-ethylenediamine (BESA) Schiff base into mesoprous SBA-15 paste for determination of trace amounts of Praseodymium (Pr) ion by UV/Vis spectrophotometry. The sensor was fabricated by dip-coating triacetylcellulose membrane into indicator solution. The proposed optical sensor was prepared through a routine procedure and characterized by various techniques such as ATR-FT-IR and SEM analyses. This optode exhibited a linear range of 10 to 190 ng mL-1 for Pr(III) ion concentration with a detection limit of 5.0 ng mL-1. The value of the response time for the newly synthesized optode was within 100 s while depending on the Pr(III) ion concentration. The proposed optode showed low detection limit, fast response time and high selectivity with respect to the group of transition metal ions (Ce 3+ , Nb 3+ , La 3+ , Cr 3+ , Zn 2+ , Hg 2+ , and Fe 2+ ions). The optode was successfully regenerated with a mixture of thiourea and NaOH solution and the response was reversible with the relative standard deviation (R.S.D.) of 1.6%. The optode was stable and stored for at least 17 days without any considerable change in its sensitivity. Finally, the developed optode was applied to determine the Pr(III) ions in spiked samples.

“…In addition, by sending a signal through an optical fibre, it is possible to miniaturize a sensor system and avoid electromagnetic interference. Based on these advantages, numerous studies have been conducted on optical sensors over approximately 50 years [18][19][20][21][22][23], and this sensing mechanism is also used to detect silver [24], dysprosium [25], gadolinium [26] and lutetium [27].…”

Instant pH sensor based on the functionalized cellulose for detecting strong acid leaks

et al. 2022

Acid spills cause large-scale environmental damage and casualties. To respond to such incidents, a sensor capable of detecting acid leaks is required. Cellulose is a useful substrate material for the fast detection of acid leaks because it has high hydrophilicity and porosity. On the other hand, methods of manufacturing cellulose-based sensors are still complicated or time-consuming. Thus, in this study, a simple and rapid synthesis method for a cellulose-based pH sensor was proposed. The functionalization of α-cellulose was achieved via chloroacetyl chloride, and Congo red was covalently immobilized to the functionalized cellulose for detecting strong acids. The manufacturing process was composed of two steps as above and finished within 8 h. The developed sensor exhibited absorbance changes in the pH range of 0.2 to 3.0, and response time was shorter than 1 s. A prototype system using this sensor was manufactured and tested, and it detected acid leaks easily and quickly.
