Example text

One of the most dangerous metal ions for human life is Cr(VI) ion which is found in industrial wastewater because of the extensive use of chromate and dichromate in electroplating, leather tanning, metal finishing, nuclear power plant, textile industries and chromate preparation. Chromium(VI) is a powerful carcinogenic agent that modifies the DNA transcription process causing important chromosomic aberrations. Cr(VI) may also cause epigastric pain, nausea, vomiting, severe diarrhea and hemorrhage.

Colleoni et al. (CRE). Ten specimens were prepared for testing, five for warp direction and five for weft direction. To thoroughly evaluate both water and oil repellency, above mentioned performances were measured after abrasion, washing and iron treatments. The samples were conditioned at 20 ± 2 °C and 65 ± 4 % RH for 24 hours before textile testing, according to standard ISO 139:2005. All measurements were repeated for the three equally treated samples and then averaged. Water and oil repellency tests were reformulated after 5 and 15 repeated home launderings carried out at 40° C, as described in the ISO 6330, followed by tumbler drying at 80° C for 20 min.
