However, a different adsorption behavior is evidenced for both materials in the presence of water vapor since HKUST-1 is very hydrophilic in the zone near to the copper open metal sites, whereas PICACTIF is hydrophobic. It begins to adsorb much earlier (0.0025 kPa) than the activated carbon (0.01 kPa). HKUST-1 has higher affinity to cyclohexane than PICACTIF for the whole pressure range studied, especially at low partial pressures. The results were compared under the same conditions for a typically used activated carbon, PICACTIF TA 60. In this work, the use of the well-known HKUST-1 MOF of different particle sizes (20 μm, 300−600 μm, and 1−1.18 mm) for the adsorption of low -grade (5000 ppm) cyclohexane combined with different water concentrations (dry, 27 and 80% RH) in a fixed bed is proposed. However, the emergence of promising novel adsorbents, such as metal−organic frameworks, has pushed the research to study their behavior under the same conditions. Historically, activated carbons are used as VOC adsorbents. VOCs can cause serious health problems in case of continuous exposure therefore, it is essential to develop efficient personal protective equipment.

You can purchase larger scale printed maps from private map retailers. The quality of the printed image will depend on the printer type, settings and paper. The maps you download from QTopo contain the same information as traditional printed maps, and you can print these on a local printer or at a print shop. The Queensland Government no longer sells printed copies of topographic maps. With QTopo, you can view Queensland's topography online, easily download pre-generated maps or create custom high-resolution topographic maps. This can be viewed online, downloaded, shared or printed at no cost to the public on an on-demand basis. QTopo is an online mapping solution that provides users with access to topographic information coverage across all of Queensland. Topographic maps are detailed representations of natural and man-made features that appear on the Earth's surface.
