Individual and simultaneous electrochemical detection toward heavy metal ions based on L-cysteine modified mesoporous MnFe2O4 nanocrystal clusters

L–Cysteine/Hydrotalcite Hybrid for Collaborative Removal of Cu(II), Hg(II) and Pb(II) Ions from Aqueous Solutions: Different Metal Ions Require Different Mechanisms

“…A strong peak around 1387 cm −1 implies NO 3 − groups existed in the interlayer of LDHs. For the FTIR spectrum of L‐cysteine and L‐cysteine/LDHs, the peaks at 1625 and 1406 cm −1 can be assigned to the asymmetric and symmetric stretching vibrations of COO − . A weak peak at 2592 cm −1 is related to the presence of S−H group in the L‐cysteine molecule .…”

Photoelectrochemical Detection of L‐Cysteine with a Covalently Grafted ZnTAPc‐Gr‐based Probe

“…Therefore, it is necessary to develop a technique for cysteine detection. L‐cysteine detection has been reported using fluorimetry , chemiluminescence , high‐performance liquid chromatography , and electrochemistry . Among these, electrochemical detection has received considerable attention owing to the high sensitivity, speed, and low cost .…”

A highly selective fluorescent probe for detection of Cd2+ and HSO3− based on photochromic diarylethene with a triazole-bridged coumarin-quinoline group

“…1,2 As we know, Cd 2+ has been widely used in many elds such as industry, agriculture, metallurgy, etc. 3,4 However, high levels of Cd 2+ can impose huge threats to the environment and human health due to its bioaccumulation through the food chain. 5,6 Excessive intake of Cd 2+ can not only increase the risk of cancer, heart disease, cardiovascular diseases and diabetes, 7-10 but also damage the liver and kidneys.…”
