Application of Poly(Acrylic Acid)‐Multiwalled Carbon Nanotube Composite for Enrichment of Rrace Hg(II)

11-Sep-2013 | Huangxin Cheng, Jitao Yu, Kefeng Zeng, Guangshun Hou, Plasma Processes and Polymers, 2013

Poly(acrylic acid)‐multiwall carbon nanotubes (PAA‐MWCNTs) was synthesized and was used as a adsorbent for the preconcentration and removal of trace Hg(II) from aqueous solution. Microwave plasma technique was used to activate MWCNT surfaces, which induces the polymerization of acrylic acid on ...

Fluoropolymer‐based clear and white paint coatings composition analysis by X‐Ray fluorescence

30-Aug-2013 | P. Ricou, K. Wood, X-Ray Spectrometry, 2013

A new method for the quantification of organic and inorganic phase fractions was developed for fluoropolymer/acrylic‐blend paints – clear and white paint coatings – on aluminum panels by using wavelength dispersive X‐ray fluorescence spectrometry (WDXRF). The method was developed for clear coat ...
