Materials, Vol. 8, Pages 1652-1665: Tuning the Pore Geometry of Ordered Mesoporous Carbons for Enhanced Adsorption of Bisphenol-A

10-Apr-2015 | Libbrecht, Wannes ; Vandaele, Koen ; De Buysser, Klaartje ; Verberckmoes, An ; Thybaut, Joris W.; Poelman, Hilde ; D ..., Materials, 2015

Mesoporous carbons were synthesized via both soft and hard template methods and compared to a commercial powder activated carbon (PAC) for the adsorption ability of bisphenol-A (BPA) from an aqueous solution. The commercial PAC had a BET-surface of 1027 m2/g with fine pores of 3 nm and less. The ...

IJMS, Vol. 16, Pages 7932-7943: Promotion of Ni2+ Removal by Masking Toxicity to Sulfate-Reducing Bacteria: Addition of Citrate

09-Apr-2015 | Qian, Junwei ; Zhu, Xiaoyu ; Tao, Yong ; Zhou, Yan ; He, Xiaohong ; Li, Daping, International Journal of Molecular Sciences, 2015

The sulfate-reducing bioprocess is a promising technology for the treatment of heavy metal-containing wastewater. This work was conducted to investigate the possibility of promoting heavy metal removal by the addition of citrate to mask Ni2+ toxicity to sulfate-reducing bacteria (SRB) in batch ...

Combining Alkaline Extraction and in Situ Plated Bismuth Film for Reliable Quantification of Zn in Multivitamin Formulations

01-Apr-2015 | Wilson T. Fonseca, Regina M. Takeuchi, André L. Santos, Electroanalysis, 2015

Abstract In this work a bismuth film electrode (BiFE) plated in situ onto glassy carbon was used to quantify Zn2+ in multivitamin formulation samples by square wave anodic stripping voltammetry. For partially water‐soluble multivitamin tablets, an alkaline extraction with 1.0 mol L−1 NaOH ...

Effect of n-Alkane Precipitants on Aggregation Kinetics of Asphaltenes

01-Apr-2015 | Nasim Haji-Akbari; Phitsanu Teeraphapkul; Arjames T. Balgoa; H. Scott Fogler, Energy & Fuels, 2015

The effect of different n-alkane precipitants on the kinetics of asphaltene aggregation is investigated in this study. When the chain length of the n-alkane precipitant, i.e., the carbon number, is increased, both the viscosity and solubility parameter of the solution increase and, as a result, ...
