“…[47][48][49] The electrochemical detection of the biosorption by using disposable PGEs is a new topic introduced in the literature by our previous report. 53 The development of microalgae-based removal system for PRL and its electrochemical detection is a new concept having several advantages explained above. But the use of low pH to obtain high removal rate could be a limitation for largescale applications.…”

Paracetamol (PRL) is an analgesic and antipyretic drug, and its consumption has increased all across the world during the COVID-19 pandemic era. However, its excessive consumption makes it an endocrine-disrupting factor, and it is toxic for the liver. It easily contaminates water resources due to its high solubility, and has substantial potential to access both aquatic life and humans. Therefore, its removal by sustainable methods is a highlighted issue for today’s world that has experienced increasing scarcity of water. Herein, microalgae-based PRL removal and its electrochemical monitoring were performed. The removal performed with Scenedesmus sp. was monitored by disposable pencil graphite electrodes and cyclic voltammetry. The removal was achieved without the requirement of complex procedures, and the monitoring of this removal finished in less than 1 min. Application of the system in real life was tested in the presence of tap water. The biosorption kinetics, isoterms, and changes in chlorophyll content of microalgae were calculated, and the microscopic characterizations of the biosorption were performed. The selectivity of the system was studied against other water contaminants. This is the first study about the removal of PRL using Scenedesmus sp. and the monitoring of the removal using disposable electrochemical sensor technology.

“…Electrochemical detection of the biosorption process.-The PRL biosorption using the microalgae was monitored using the cyclic voltammetry (CV) technique. 53 For this purpose, 2 ml of the sample was transferred into the electrochemical cell. The potential range was between +0.30 V to +1.20 V and the scan rate as 50 mV s −1 .…”
