An application of miniaturized electrochemical sensing for determination of arsenic in herbal medicines

Abstract

This study aimed to create a miniaturized electrochemical platform for detecting As(III) contamination in herbal medicines. To reduce the operational steps of modification and determination, only a single drop of...

Hybridized sulfated-carboxymethyl cellulose/MWNT nanocomposite as highly selective electrochemical probe for trace detection of arsenic in real environmental samples

“…Additionally, it impairs immune function in pregnant women, increasing the chance of newborn mortality. 4 The World Health Organization recommends that the As(III) concentration in drinking water be less than 10 mg L −1 and in surface water be less than 50 mg L −1 , respectively, due to its severe toxicity. 5,6 Therefore, it is particularly important to determine the trace levels of As(III) in natural water (rivers, sea, and ocean), wastewater (from pesticides, chemicals, metal processing, and mining, etc.…”
