Electrochemical Removal of Algestone Acetophenide and Estradiol Enanthate in Real Industrial Wastewater

Abstract

Contaminants removal from industrial effluent is a major environmental concern. In this context, Algestone Acetophenide and Estradiol Enanthate are synthetic sex hormones widely used in the manufacture of contraceptives, whose presence in waterbodies may lead to environmental hazard. Given that so far, the methods employed in the removal of these drugs have presented limited efficiency or high implementation costs, the present work presented an electrochemical reactor composed by 32 carbon steel electrodes (1728 cm 2), which was employed in a real scale model to remove these synthetic hormones in an industrial pharmaceutical effluent. After 60 minutes the removal efficiency of the hormones Algestone Acetophenide and Estradiol Enanthate was of 88.9% and of 91.8% respectively, with low energy consumption (< 0.742 kWh.m-3). Physicochemical parameters such as color, turbidity, Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) also showed good removal efficiency too (> 50%), which implicates that the method herein depicted may be a valuable alternative to promote the removal of these contaminants in industrial wastewater.

Electroanalysis of Oenological Products for Fingerprinting: a Brief Overview

“…For example, cyclic voltammetry can characterise phenolic compounds' redox behaviour ], while differential pulse voltammetry can enhance sensitivity and selectivity for trace analysis [37]. Furthermore, voltammetry has been proven to allow susceptible and selective compound detection and is increasingly used in chemical and pharmaceutical industries for quality control [31,[38][39][40] and environmental monitoring [41][42][43].…”

“…In practical applications, this electrochemical transduction process offers numerous advantages. It enables real-time and rapid detection of target analytes with high sensitivity and selectivity, making it ideal for applications in healthcare [28][29][30], environmental monitoring [31][32][33][34][35][36][37][38][39][40][41], food safety [42][43][44][45][46][47][48][49], and pharmaceutical research [50][51][52][53][54][55]. This field's continuous research and development strives to further optimise the electrochemical transduction process, aiming for enhanced performance, increased versatility and expanded applications across a broad spectrum of analytical domains.…”
