The invention comprises a method of processing a waste stream containing dyes, such as a dye bath used in the textile industry. The invention comprises using an inorganic-based polymer, such as polyphosphazene, to separate dyes and/or other chemicals from the waste stream. Membranes comprising polyphosphazene have the chemical and thermal stability to survive the harsh, high temperature environment of dye waste streams, and have been shown to completely separate dyes from the waste stream. Several polyphosplhazene membranes having a variety of organic substituent have been shown effective in removing color from waste streams.

[ I claim:] [1.] A method of separating a dye from an aqueous stream, the method comprising:contacting a phosphazene polymer with an aqueous stream comprising a dye, so that the dye is substantially prevented from permeating through the phosphazene polymer; andcollecting a permeate stream comprising water that has permeated through the phosphazence polymer.
