Definition

Meaning and Definition

To subject a solution or mixture to dialysis; to separate or purify (a substance) using a semipermeable membrane.

In a broader technical sense, to use a membrane-based process to remove small molecules or ions from a solution, typically to cleanse waste products from blood in renal failure (haemodialysis). The term can also be used metaphorically in analytical contexts to describe a careful, systematic separation of components.

Dialectal Variation

British vs American Usage

Differences

Spelling: The British English spelling is 'dialyse' (with an 's'). The American English spelling is 'dialyze' (with a 'z'). Pronunciation differences follow the IPA provided.

Connotations

Identical in meaning and technical connotation. Usage is equally rare and specialised in both varieties.

Frequency

Extremely low frequency in both. The noun 'dialysis' and the verb form 'undergo dialysis' are far more common than the active verb 'to dialyze/dialyse' in patient contexts.

FAQ

Frequently Asked Questions

Dialyze specifically involves a semipermeable membrane where separation occurs via diffusion of solutes based on molecular size. General filtering uses a physical barrier (like a paper filter) to separate particles based on size, often without a concentration gradient driving the process.

No. Patients and even healthcare staff more commonly use the noun 'dialysis' in phrases like 'undergo dialysis', 'receive dialysis', or 'be on dialysis'. The active verb 'dialyze' is more common in laboratory and technical writing.

The British spelling is 'dialyse' (with an 's'), following the pattern of 'analyse', 'paralyse' etc.

Yes, but still in technical contexts. In biochemistry and chemistry, it is standard to describe the purification of macromolecular solutions (like proteins) by dialyzing them against a buffer to remove salts or other small molecules.
