Abstract Electrochemical disinfection is a broad spectrum, efficient, clean, and environment-friendly, widely used in water treatment technology. In addition to the active chlorine generated by electrolysis, oxidation of oxygen free radicals cannot be ignored. this paper, electron spin resonance (ESR) technique measure ESR spectra ·OH. 1 O 2 , - that may exist during electrolysis process after ...

Gallic acid (GA) is the main phenolic antioxidant which has been subjected of many studies because of its important biological properties including anticancer, anti-inflammatory and antimicrobial activities as well as free radicals scavenger and cardiovascular diseases protector. Hereupon, fabricating a selective and sensitive sensor for GA detection and measurement is an important issue. In th...

Electroanalytical methods enable determination of electroactive species in nonhomogeneous systems, as limiting currents are little affected by the presence of solid and colloidal particles. An example of such applications of electrochemical methods are studies of binding of toxic substances, such as pesticides, on slightly soluble polymers, such as lignin. To successfully apply polarographic me...

In this paper, we report a novel electrochemical method that can be developed as a biosensor for simple and direct determination of α-amylase activity. The method is based on the hydrolysis of maltopentaose, the substrate of the enzyme, which is immobilized on the surface of a gold electrode, and the induced charge changes of the substrate-modified electrode. Specifically, the substrate maltope...

A facile electrochemical sensor for hydroquinone (HQ) and catechol (CC) determination was successfully fabricated by the modification of poly(3-aminophenylboronic acid) (pAPBA) film and multi-walled carbon nanotubes (MWCNTs) on a glassy carbon electrode (pAPBA/MWCNTs/GCE). The prepared sensor was characterized by scanning electron microscope and electrochemical impedance spectroscopy. Under opt...
