Abstract:
High sensitivity of lead to organic compounds leads to degradation of lead artifacts stored in the museums or archives together with organic materials (wood, glue, leather, paper, plastic, etc.). Protection of the lead stored under adverse conditions (environment polluted by organic compound, mainly acetic acid) is based on the use of corrosion inhibitors. [..]
