Article Synopsis
  • A bioadsorbent made from wattle humus was created to remove fluoride from contaminated environments using a thermal activation process, showing significant potential for fluoride adsorption.
  • Analytical techniques confirmed that the wattle humus can effectively adsorb fluoride through chemisorption, achieving up to 98% removal efficiency under optimal conditions (pH > 6).
  • Experiments examined various factors affecting adsorption, including initial fluoride concentration, contact time, adsorbent dosage, and presence of other ions, while also demonstrating that the adsorbent retains high effectiveness even after multiple uses.

Predominantly, the removal of dissolved contaminates via the Fe electrocoagulation (EC) process depends on the electrocoagulants stability, specific area, porosity, dissolution rate, and phase transformation kinetics. The present investigation elucidates the role of applied currents and electrolyte counteranions on the crystalline phase and surface topography of electrocoagulants generated from Fe EC. Moreover, the dissolved contaminant micropollutant removal efficiency was also evaluated by electrochemically produced coagulants.

This is a first review paper that delineates fundamental disinfection mechanism undergoes during the simple electrochemical coagulation (EC) process. The elucidation of detailed mechanistic phenomenon of EC process involved would help to enhance the disinfection efficiency. In this context, the biomass (bacteria, virus and algae) abatement mechanism by EC is critically reviewed and rationalized based on the experimental demonstration performed from the recent decade.

The present study is aimed to evaluate the protective effect of ferulic acid (FA) on fluoride-induced oxidative hepatotoxicity in male Wistar rats. Fluoride (25 mg/L) was given orally to induce hepatotoxicity for 12 weeks. Hepatic damage were assessed using status of pathophysiological markers like serum marker enzymes like aspartate transaminase, alanine transaminase, alkaline phosphatase, acid phosphatase, gamma glutamyl transferase, lactate dehydrogenase, bilirubin, lipid profile, total protein content levels, and histopathological studies.
