Anthropogenic pollutant of sugarcane based distilleries, is one of the major source of environmental pollution like air, water, soil & its disposal is challenging due to pH, colour, solid content, inorganic & organics compounds. The estimation of Basic, Neutral & Acidic SVOCs presents challenges due to the simultaneous measurement of compounds over a wide concentration range. The accelerated solvent extraction (ASE) method involves sample extraction with methylene dichloride & concentrate solvent extracts by using Kuderna-Danish (K-D) concentrator glassware tool. The ASE method is simple, faster, more expedient & cost effective than previously available methods which require tedious sample preparation with complex sample holders. The study allowed obtaining qualitative identification and distribution of base, neutral & acidic SVOCs of Indian sugarcane distillery effluent was studied by using GC-MS. The GC-MS profile of Basic, Neutral & Acidic SVOCs in the range of 100-200 amu are prominently observed in juice, raw and biomethanated spentwash sample. Neutral SVOCs are conspicuous in juice (68.18%) and biomethanated (56.03%) spentwash sample in MW range of 100-500 amu. Acidic SVOCs are prominent in raw (53.45%) spentwash sample in MW range of 100-500 amu. The overall percentage of SVOCs leads to pH of spentwash sample.
