The iodine content and thus the active chlorine content can be determined with iodometry.

The attempt failed because of the high chlorine content in the treated water at the camp.

In 2004, however, the formula was changed to low density polyethylene due to environmental concerns about its chlorine content.

After the pool has been properly shocked, he said, the chlorine content should be maintained at a level of 1 to 2 parts per million.

The pool should be shocked at least once a month or whenever the chlorine content falls below the recommended level, he added.

PVC can be usefully modified by chlorination, which increases its chlorine content to 67%.

Oxygen concentration also plays a major role on dioxin formation, but not the chlorine content.

The colder the water, the higher the chlorine content.

An important aspect in this connection is the high chlorine content.

The chlorine content of the water would be no greater than that of the county's drinking water.
