Enhanced Degradation of Micropollutants in a Peracetic Acid-Fe(III) System with Picolinic Acid.

Environmental Science and Technology, 2022
Activation of peracetic acid (PAA) with iron species is an emerging advanced oxidation process (AOP). This study investigates the use of the chelating agent picolinic acid (PICA) to extend the pH range and enhance the performance of the PAA-Fe(III) AOP ...

Mn(II) Acceleration of the Picolinic Acid-Assisted Fenton Reaction: New Insight into the Role of Manganese in Homogeneous Fenton AOPs.

Environmental Science and Technology, 2022
The homogeneous Fe-catalyzed Fenton reaction remains an attractive advanced oxidation process for wastewater treatment, but sustaining the Fe(III)/Fe(II) redox cycle at a convenient pH without the costly input of energy or reductants remains a challenge.

The Fenton Reaction in Water Assisted by Picolinic Acid: Accelerated Iron Cycling and Co-generation of a Selective Fe-Based Oxidant.

Environmental Science and Technology, 2021
The Fenton reaction is limited by a narrow acidic pH range, the slow reduction of Fe(III), and susceptibility of the nonselective hydroxyl radical (HO•) to scavenging by water constituents.

2-Picolinic acid as a naturally occurring hydrogen bond donor for the preparation of cyclic carbonates from terminal/internal epoxides and CO2

Green Chemistry, 2022
Naturally sourced 2-picolinic acid was discovered as an off-the-shelf, non-toxic, and inexpensive HBD catalyst for the cycloaddition of CO2 to both internal and terminal epoxides to prepare cyclic carbonates at low catalyst loadings.
