The phrase "atomic absorption technique" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly in chemistry or analytical methods, to refer to a specific technique for measuring the concentration of elements.
Example: "The atomic absorption technique is widely used for analyzing trace metals in environmental samples."
Alternatives: "atomic absorption method" or "atomic absorption analysis".
The concentrations of heavy metal (Pb2+) under study were determined by the atomic absorption technique type AA-6800, Shimadzu, Japan.
Effluent samples from the column were collected at specified time intervals, and remaining lead concentrations in the solution were measured by atomic absorption technique.
In most of the cases, the values obtained with this technique agree fairly well with those obtained from the analysis by atomic absorption technique.
