Developing predictive models for iodo-trihalomethane (I-THM) formation in water is needed and valuable to minimize extensive and costly analysis. The main objective of this study was to develop a statistical model for the formation of six types of I-THMs under uniform formation conditions. Prediction of I-THM formation in two different water sources (natural organic matter [NOM] and algal organic matter [AOM]) were comprehensively evaluated during both preformed chloramination and prechlorination followed by ammonia addition conditions.

In this study, sequential adsorption and electro-regeneration of ciprofloxacin (CIP)-laden carbon were investigated using both pristine and iron (Fe)-doped F400 activated carbon in distilled, deionized (DI) water and reverse osmosis (RO) concentrate water. The impact of reactor flow rate and sequential adsorption/electro-regeneration cycles on the regeneration efficiency were also evaluated.

Among the techniques used during tertiary wastewater treatment, adsorption is an effective and cost-efficient method for removing antibiotics. This study aimed to investigate the adsorption of ciprofloxacin (CIP) on metal-doped granular activated carbon (GAC) and evaluate the impact of urine on CIP adsorption for pristine, pre-oxidized, and metal-doped GAC.

- Adsorptive separation technologies are effective for removing organic contaminants from water, but the regeneration of spent adsorbents is crucial due to inevitable breakthrough of contaminants.
- Electrochemical regeneration is highlighted as a promising method that allows for in situ regeneration, eliminating the need for hazardous chemicals and the transportation of spent adsorbents.
- The review assesses the fundamental principles of electro-regeneration, discusses its application to emerging contaminants like PFAS, and identifies future research areas to improve these methods.
Convalescent plasma for COVID-19 in the intensive care unit.
Anaesthesiol Intensive Ther
February 2022
Introduction: We aimed to investigate the clinical features and mortality of critically ill patients treated with convalescent plasma for COVID-19 in the intensive care unit (ICU).
Material And Methods: We retrospectively collected clinical and laboratory data of COVID-19 patients treated in the ICU. The patients were divided into two groups: those who received convalescent plasma and those who did not.
