Water organic pollution has become a major issue. A large number of people suffer from the decline in water quality. In addition, polluted water can lead to health problems or excessive deaths. In this regard, an increasingly important method for efficient water treatment is electrocoagulation (EC), the technology that encompasses a small equipment size combined with a simple operation compared to other water treatment methods. The importance of EC is especially accentuated by the recent decarbonization efforts due to the increasing availability of renewable electricity systems. This review provides an overview of the most recent developments in EC technology as it pertains to wastewater treatment. The EC is preferred for organic wastewater treatment over other traditional treatment methods due to its easy setup and low material costs. Moreover, the EC is very powerful in destabilizing organic impurities by charge neutralization and then coagulating to form flocs. In addition, EC has shown high efficiency not only in removing various organic pollutants but also in emerging persistent contaminants, such as microplastics. For these reasons, the EC mechanisms and related functional modalities are reviewed, as well as extensive details are provided on the diversity of the removed contaminants. Overall, this review provides significant new knowledge of interest for environmental chemical researchers in particular and engineers in general on the details of the EC technology for wastewater treatment and water purification.

“…2,3 In recent decades, the emergence of steroid hormones in water resources received global attention because they can mimic or block the endogenous hormones at low concentrations of ng•l −1 , leading to a number of health problems, [4][5][6][7] such as obesity, lower sperm counts in men, testicular cancer, prostate cancer, ovarian cancer, breast cancer, etc. 8,9 Unfortunately, the steroid hormones have been detected in freshwater in different countries, such as America, Germany, Japan, Brazil and China. 5,8,10 As reported, these contaminants are mainly derived from the human and animal excretion or pharmaceutical industrial wastewater.…”

The existence of hydrocortisone in water resources is a serious threat to human health. However, the rapid and sensitive detection methods for hydrocortisone in wastewater are still lacking. Meanwhile, due to the weak redox activity of hydrocortisone, electrochemical technique cannot be used to detect hydrocortisone directly. Therefore, molecularly imprinted technique combined with prussian blue nanoparticles was synthesized for detecting HC indirectly in this work. We fabricated a novel and highly sensitive molecularly imprinted sensor based on the polydopamine/electro-reduced graphene oxide, which was used for the specific recognition of hydrocortisone in water samples. The prussian blue nanoparticles were introduced as probes to reflect the concentration of the target. The morphology of the prepared sensors was characterized by the scanning electron microscopy. And the feature of the imprinted electrode was performed by the cyclic voltammetry and differential pulse voltammetry. Under the optimal experimental conditions, the relative current signal of prussian blue decreased linearly with the increase of hydrocortisone concentration with a limit of detection 0.006 nM. Moreover, the imprinted sensor had a much higher affinity towards hydrocortisone than other analogues. Then, this system was successfully applied to determine hydrocortisone in real wastewater samples with workable results.
