The phrase "and pretreated in a" is correct and usable in written English.
It can be used in contexts where a process or treatment is being described, particularly in scientific or technical writing.
Example: "The samples were collected and pretreated in a solution to enhance their reactivity before analysis."
Alternatives: "and processed in a" or "and conditioned in a".
