Abstract:	The effects of trisodium nitrilotriacetate (SKTA) and sodium tipolyphosphate (STPP) upon the biological degradation of linear alkyl benzene sulfonate (LAS) ware experimentally investigated by the chemical oxygen demand and methylene blue methods. It was found that when STPP was present with LAS, the degradation of the LAS was better than when alone in solution. It was also found that LAS in solution with SN TA was less degradable than LAS alone. The benzene ring of the MS appeared to degrade after most of the linear portion of the chain had already been degraded.
