Worldwide consumption, toxicity, and bioaccumulation of paracetamol (PCM) and atenolol (ATL) has drawn attention of researchers over last decades. A small portion of these drugs is absorbed by human body and rest of them is excreted through urine and feces to the environment (water bodies and soil) which might result in negative impacts. Nanocomposite of chromium oxide coupled with zinc hexacyanocobaltates (Cr 2 O 3 @ZnHCC) was synthesized by a green-method using Sapindus mukorossi seed-extract for the removal of targeted drugs. Microscopic and spectroscopic analysis of Cr 2 O 3 @ZnHCC showed uniformly incorporated prisms into cubic structure having ~75 nm particle size. Well-characterized Cr 2 O 3 @ZnHCC and individuals (Cr 2 O 3 & ZnHCC) were utilized for the degradation of PCM and ATL under direct sunlight and dark conditions. Highest degradation of targeted drugs (91%-94%) resulted at 20 mg L À1 concentration of pollutant, 25 mg of catalyst dose, and pH ~7 under daylight exposure (5 h). First-order kinetics followed with a high adsorption capacity, X m (13.4-14.5 mg g À1 ) value was obtained to confirm the strong binding with the pollutants. Moreover, Cr 2 O 3 @ZnHCC substantially suppressed the half-life of targeted drugs (PCM: 0.6 h; ATL: 2.9 h) and converted them into safer-small metabolites as confirmed by liquid chromatography-mass-spectrometry analysis, and the reduction of carbon content was confirmed by total organic carbon analysis. The charge separation mechanism was assisted by UV reflectance and photoluminescence data. The synthesized green-nano photocatalyst displayed high reproducibility (up to 10th cycle), sensitivity, and stability during the degradation process which makes this a suitable candidate for industrial 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.
