摘要： Described are filter materials including a polyol ligand, such as n-methylglucamine, and/or a polyphosphonic acid ligand, which are highly effective for filtering metals or metal ions from fluids. The filter materials can be particularly useful to filter basic and acidic fluid compositions, such as those used for wet etching, removing photoresist, and cleaning steps in microelectronic device manufacturing.

摘要： Described are filter materials having polycarboxyl ligands, such as iminodiacetic acid, which are highly effective for filtering metals or metal ions from fluids. The filter materials can be particularly useful to filter various fluid compositions, such as those used for wet etching, removing photoresist, and cleaning steps in microelectronic device manufacturing.
