PURIFICATION IS REMOVAL. 'Deleading' frames the process as extracting a harmful agent to restore purity/safety.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'deled' or a past tense form of an unrelated verb. It is a specific technical term.
- The Russian equivalent would be a phrase like 'удалять свинец' or 'обессвинцовывать' (technical), not a single common verb.
Common Mistakes
- Misspelling as 'dealed' or 'de-led'.
- Using it as a general term for cleaning (it is highly specific).
- Incorrect stress: it is 'de-LEAD', not 'DEE-leed'.
