Sustainable replacement of EDTA-Biojarosite for commercial iron in the Fenton's and UV-Fenton's degradation of Rhowedamine B - a process optimization using Box-Behnken method.

Biojarosite as a replacement for commercial iron catalyst in the oxidative degradation of the dye Rhodamine B was confirmed and established. Investigations on the oxidative degradation by Fenton's oxidation and UV-Fenton's oxidation with EDTA at neutral pH were conducted and degradation of target compound was evaluated. UV-Fenton's oxidation was shown to be efficient over Fenton's oxidation in the degradation of Rhodamine B with removal efficiency of 90.

Evaluation of risk factors for prognosticating blunt trauma chest.

<b>Introduction:</b> Blunt trauma chest contributes to significant number of trauma admissions globally and is a cause of major morbidity and mortality. Many scoring systems and risk factors have been defined in past for prognosticating blunt trauma chest but, none is considered to be gold standard. </br> <b>Aim:</b> This study was conducted to reassess the significance of available scoring systems and others indicators of severity in prognosticating blunt trauma chest patients.

Sustainable treatment of paint industry wastewater: Current techniques and challenges.

Paint manufacturing industries produce wastewater containing high chemical oxygen demand and turbidity, besides organic matter, suspended solids, and heavy metals that cause enormous environmental damages. Safely treating this wastewater before being disposed to the natural water sources is essential for attaining the UN SDGs, particularly Goal 14: Life under water. Besides being efficient, wastewater treatment techniques must be sustainable - environmentally, economically, and ethically.

Bioleaching of iron from laterite soil using an isolated Acidithiobacillus ferrooxidans strain and application of leached laterite iron as Fenton's catalyst in selective herbicide degradation.

A novel isolated strain Acidithiobacillus ferrooxidans BMSNITK17 has been investigated for its bioleaching potential from lateritic soil and the results are presented. System conditions like pH, feed mineral particle size, pulp density, temperature, rotor speed influences bioleaching potential of Acidithiobcillus ferrooxidans BMSNITK17 in leaching out iron from laterite soil. Effect of sulfate addition on bioleaching efficiency is studied.
