Sustainable adsorptive removal of antibiotics from aqueous streams using FeO-functionalized MIL101(Fe) chitosan composite beads.

In this study, we synthesized recyclable FeO-functionalized MIL101(Fe) chitosan composite beads for the removal of tetracycline (TC), doxycycline (DC) and ciprofloxacin (CFX) antibiotics from aqueous streams. More than 99% removal efficiency for each antibiotic was achieved at optimum pH, dosage, concentration and contact time. Langmuir adsorption isotherms and pseudo-second-ord er kinetic model were suitable with correlation coefficient values close to 1 for all the antibiotics.

Adsorption of cupric, cadmium and cobalt ions from the aqueous stream using the composite of iron(II,III) oxide and zeolitic imidazole framework-8.

In recent research, the composite of FeO and metal-organic frameworks have shown great potential in removing potentially toxic metals from water. We conducted the adsorption studies of potentially toxic metal ions (Cu, Co and Cd) using the composite of FeO and zeolitic imidazole framework-8 (FeO@ZIF-8) for the first time. The solvothermal technique was used to synthesize the FeO.

Implementation of water safety plan for a large-piped water supply system.

A water safety plan for the city of Nagpur was developed by the National Environmental Engineering Research Institute (NEERI) and Nagpur Municipal Corporation (NMC). Possible hazards were identified through field visits. Based on this, an improvement plan was drawn up to suggest corrective actions and a time frame for implementation.
