Chemical and wettability studies on coal, humic acid and cyclized humic acid
Fuel, 1989 Abstract Investigation of properties such as wettability of coal is often complicated by variations in the surface chemistry of coal samples during their preparation, storing and pretreatments. It is the aim of this study to prepare hydrophobic and hydrophilic derivatives of a single parent coal by chemical methods selected for rupturing and closing ...

Humic acid removal by electrocoagulation: characterization of aluminum species and humic acid
Desalination and Water Treatment, 2016 In this study, the different aluminum (Al) species generated during electrocoagulation (EC), the humic acid (HA) removal, and the change in HA characteristics were evaluated. The results show that the distribution of monomeric Al species (Ala), medium polymer Al species (Alb), and colloidal or solid Al species (Alc) was dependent on initial pH and ...
