Extraction of Organic Compound from Carboxymethyl Cellulose Wastewater

Abstract:

Carboxy methyl cellulose (CMC) wastewater contains high salinity (>10%) and chemical oxygen demand (COD) which results from organic by-products during production. It is usually necessary that the wastewater is pretreated before biochemical methods are employed. In this paper, distillation method was used to pretreat CMC wastewater and a kind of organic acid (Ethoxyacetic acid) was extracted. Effect of solution pH on the purity of ethoxyacetic acid was studied.
