Adsorbent screening for airborne BTEX analysis and removal

BTEX Removal from Natural Gas Streams

Airborne Mycotoxin Sampling and Screening Analysis

The indoor mycotoxins inhalation exposure of patients (n=25) was studied using a highvolume air sampler (60 cfm x 24 h) with a micropore-paper filter (8x11 inches). The filters were evaluated for cytotoxicity caused by mycotoxins using the MTT-cell culture bioassay and by culture identification. A subset of samples was analyzed with an enzyme-immuno assay for occurrence of macrocyclic trichothe...

Role of activated carbon from natural adsorbent for removal of textile dyes: effect of pH, kinetic and adsorbent mass

In the present work, we have investigated the sorption efficiency of the treated activated carbon from walnut shell(ACW) towards Direct Red 81 (DR81) and Direct Blue 71 (DB71) for the removal from aqueous solution. Thesorption study of ACW at the solid-liquid interface was investigated using kinetic, sorption isotherms, pH effectand amount of adsorbent. Experimental data were analyzed by Langmu...

Dewatered alum sludge: a potential adsorbent for phosphorus removal.

Alum sludge refers to the by-product from the processing of drinking water in water treatment works. In this study, groups of batch experiments were designed to identify the characteristics of dewatered alum sludge for phosphorus adsorption. Air-dried alum sludge (moisture content 10.2%), which was collected from a water treatment works in Dublin, was subjected to artificial P-rich wastewater a...

Nanocrystalline Akaganeite as Adsorbent for Surfactant Removal from Aqueous Solutions

The present study presents the effective use of nanocrystalline akaganeite for the adsorption of an anionic (SDS), a cationic (CTAB), and a nonionic (tween80) surfactant from wastewater. Equilibrium experiments, as well as thermodynamic analysis, were performed. The maximum SDS adsorption occurs at the lowest pH value (5), the opposite is observed for CTAB (pH = 11), while for tween80, the chan...
