Enhanced Adsorption

Adsorption of ionizable aromatic compounds (IACs) such as 1-naphthylamine and 1-naphthol on Humic acid (HA)-coated graphene oxide nanosheets (GONs), multiwalled carbon nanotubes (MWCNTs), activated carbon (AC), and flake graphite (FG) were investigated by the batch techniques.

Refractory Organic Matter

Biological powdered activated carbon (BPAC) was incorporated with a microfiltration (MF, 0.2 μm pore size) system to remove the refractory organic matter contained in secondary sewage effluent. A synthetic secondary sewage effluent was used as influent in this study, containing both non-biodegradable organic substances (such as humic acid, lignin sulfonate, tannic acid and arabic gum powder) and biodegradable ones. These refractory organic materials were possibly degraded in contact with microorganisms for 20-27 days. Although humic acid and arabic gum were weakly adsorbed on the activated carbon, they could be effectively removed in the BPAC reactor. The TOC removal at a powdered activated carbon (PAC) concentration of 20 g/L was higher than at 0.5-2 g PAC/L (83% and 66-68%, respectively). The higher removal efficiency was due to the increased rejection at the membrane module in which most of the PAC was accumulated. More than 90% of non-biodegradable compounds removal (detected as E280 , UV absorption at 280 nm) occurred in the BPAC reactor. The biological growth parameter b/Y, used in system design, was estimated to be 0.017 d-1. Relatively high permeate flux of 1.88 m/d could be obtained even at higher PAC concentration of 20 g/L.

Continuous Adsorption

The adsorption of humic acids on granular activated carbon has been investigated. A commerically available humic acid and that extracted from the bottom sludge of a dam were employed in the studies. Both batch and continuous adsorption experiments were conducted. A simplified competitive adsorption model in conjunction with the Freundlich isotherm was employed to represent the batch multicomponent adsorption system and a homogeneous surface diffusion model utilized to describe the continuous adsorption system in a packed-bed column. The model parameters were obtained by best fit of the models to the experimental adsorption data. The results indicated that the liquid-phase mass-transfer resistance, surface diffusion coefficient and the amount of adsorption on the activated carbon decreased with increasing molecular weight of the humic acid. It was also found that the adsorption of humic acid on the activated carbon was primarily a surface diffusion-controlled process.
