chlorine residual testing

Chlorine Residual Testing

Digital colorimeters are the most accurate way to measure free chlorine and/or total chlorine residual in the field in developing countries. hese colorimeters use theT following method: 1) addition of DPD tablets or powder into a vial of sample water that causes a color change to pink; and, 2) insertion of the vial into a meter that reads the

study on the leaching of phthalates from polyethylene terephthalate

Study on the leaching of phthalates from polyethylene terephthalate

The concentration range of DiBP, DBP, BBP, DEHP in all investigated non-carbonated mineral water samples was: < LOQ — 0.2 μg L − 1, < LOQ — 0.8 μg L − 1, < LOQ — 0.1 μg L − 1 and < LOQ — 1.7 μg L − 1, respectively. With respect of the investigated phthalates, the highest concentrations were observed for DEHP in each water ...

k-25

K-25

K-25 was the codename given by the Manhattan Project to the program to produce enriched uranium for atomic bombs using the gaseous diffusion method. Originally the codename for the product, over time it came to refer to the project, the production facility located at the Clinton Engineer Works in Oak Ridge, Tennessee, the main gaseous diffusion building, and ultimately the site.

Study of the Migration of Stabilizer and Plasticizer from Polyethylene

The thickness of samples were measured at five points spread out over the sample using a DRK 203B digital thickness meter (Derek Instrument Co., Ltd, Jinan, China), and the mean value of the samples were in the range of 0.215–0.239 mm. Density of the samples were in the range of 1.41–1.50 g cm −3.
