Thallium is a heavy metal highly toxic to the biosphere. It can be determined by anodic stripping voltammetry after deposition on mercury film. The aim of this work is to study the conditions and mechanisms of deposition of Hg on glassy carbon electrode and Tl on Hg film by cyclic voltammetry, scanning electron microscopy, chronoamperometry and impedance techniques. The results showed a germination and growth of a 3D Hg phase on glassy carbon electrode. Similarly, the electrodeposition of Tl on Hg follows a 3D three-dimensional nucleation with diffusion controlled growth. The impedance measurements reveal an easier charge transfer on the Tl film.

“…Salah satu senyawa kimia hasil limbah industri yang harus dideteksi keberadaannya didalam perairan adalah Hidrazina (N2H4). Hidrazina merupakan senyawa kimia yang banyak digunakan pada industri kimia, pertanian, fotografi, fuel-cell, dan luar angkasa [6]. Hidrazina dikategorikan sebagai senyawa yang bersifat neurotoksin dan diklasifikasikan kedalam golongan yang mutagenik dan karsinogenik [7].…”

Hidrazina merupakan senyawa kimia berbahaya yang banyak digunakan pada berbagai industri. Keberadaan senyawa ini pada perairan hasil buangan limbah industri haruslah dimonitor dan dikontrol keberadaannya. Untuk itu diperlukan suatu sensor yang dapat digunakan untuk mendeteksi keberadaan senyawa ini didalam perairan. Elektroda karbon komersil merupakan material yang ramah lingkungan dan harganya relatif murah untuk dijadikan material sensor yang potensial, akan tetapi material ini memiliki aktivitas elektrokimia yang rendah dan bersifat hidrofobik. Untuk meningkatkan aktivitas elektrokimia elektroda karbon, maka modifikasi dilakukan dengan menggunakan material CuS-Nafion dan CuS@rGO-Nafion yang disintesa melalui reaksi solvotermal dan di drop-casting pada permukaan elektroda karbon. Modifikasi berhasil dilakukan yang ditunjukkan oleh hasil scanning electron microscopy dimana memiliki respon yang tinggi terhadap senyawa hidrazina yang ditunjukkan dari hasil analisa cyclic voltammetry (CV). Hasil terbaik ditunjukkan oleh elektroda karbon yang dimodifikasi dengan menggunakan material CuS@rGO-Nafion. Hasil electrochemical impedance spectroscopy (EIS)nya menunjukkan hasil yang sangat baik dimana nilai Rctnya adalah sebesar 2178 Ω yang dapat memfasilitasi perpindahan elektron yang tinggi pada permukaan elektroda yang dimodifikasi.

A novel colorimetric fluorescent probe for detecting hydrazine in living cells and zebrafish

et al. 2022

Hydrazine (NH 2 NH 2 ) is a highly toxic organic substance that poses a threat to human health. Monitoring hydrazine with high sensitivity and selectivity is very important.Here, a simple colorimetric fluorescent probe for hydrazine detection, which is a seminaphthorhodafluor derivative containing thiophene-2-carboxylic acid ester reaction site, was rationally constructed. The probe itself exhibits weak fluorescence. The fluorescence is significantly enhanced when hydrazine is added. The probe exhibited a broad linear range (0-1 mM) with satisfactory selectivity and sensitivity (limit of detection 36.4 μM), which turned out to be an excellent fluorescent probe for monitoring hydrazine. Additionally, the probe was used to track hydrazine in living cells and zebrafish with great success, and the detection performance was satisfying.These results proved that this type of fluorescent probe with the thiophene-2-carboxylic acid ester structure can detect hydrazine with higher selectivity and sensitivity.
