Sodium hydroxide (NaOH) and oxalic acid (OA) were selected as the alkaline and acid additives, respectively, to investigate whether acid and alkaline additives could promote oxidative desulfurization in the UVH 2 O 2 system. The coal samples were investigated via scanning electron microscopy (SEM)...
acid), it is readily oxidized; this makes it useful as a reducing agent for photography, bleaching, and ink removal. Oxalic acid is usually prepared by heating sodium formate with sodium hydroxide to form sodium oxalate, which is converted to calcium oxalate and treated with sulfuric acid to ...

Enolized β-diketones can be deprotonated using a base such as sodium hydroxide which thus provides an ion exchange site for Li during the extraction [28]. Since Li has a higher positive charge and smaller size compared to Na it acts as a hard acid and binds strongly with the conjugate ...
