Indoor formaldehyde removal over CMK-3
The removal of formaldehyde at low concentrations is important in indoor air pollution research. In this study, mesoporous carbon with a large specific surface area was used for the adsorption of low-concentration indoor formaldehyde. A mesoporous carbon material, CMK-3, was synthesized using the nano-replication method. SBA-15 was used as a mesoporous template. The surface of CMK-3 was activat...
متن کاملRemoval of indoor formaldehyde over CMK-8 adsorbents.
CMK-8, a mesoporous carbon material, was activated using different methods for the adsorption of low-concentration airborne formaldehyde. KOH and ammonia treatments were used to activate CMK-8. A CMK-8 sample was treated with KOH first followed by an ammonia-treatment at 700 degrees C to determine the effect of a combination of the two treatment methods. The adsorbents prepared were characteriz...

متن کاملFormaldehyde as Screen Printing Indoor Pollutant
The presence of formaldehyde in indoor air samples has been detected in five screen printing facilities of Novi Sad, Serbia. Air was sampled five times during one working week for each screen printing facility. The sampling was conducted continuously during 4 hours. The concentrations of formaldehyde were determined by UV-VIS spectrometry at 580 nm. The average concentrations of formaldehyde we...
متن کاملBadge-type diffusive sampler using 3-methyl-2-benzothiazolinone hydrazone for measuring formaldehyde in indoor air.
The evaluation of a badge-type diffusive sampler for measuring formaldehyde using 3-methyl-2-benzothiazolinone hydrazone (MBTH) was investigated. On average, the formaldehyde concentration in blanks was reduced by approximately 31% by cleaning procedures. The cleaning techniques did not significantly differ in effectiveness. The maximum sampling rate was 22.4 +/- 3.5 mL min(-1) at MBTH concentr...
