The processing of starch involves all process stages including the storage of the starch powder, dispersing, gelatinization, and thinning for the intended usage. At the starch preparation starch powder and water are suspended into slurry and cooked depending on the applictaion.
Objective: To measure the paraquate (Pq) levels in urine and serum of patients with sodium dithionite in order to predict the outcome of patients after paraquart intoxication. Method: Standard colorimetry and standard curve for paraquat measurement was established using sodium dithionite to react with paraquat in different concentrations and in alkaline medium.
Sodium dithionite or sodium hydrosulfite/Blankit (Na 2 S 2 O 4) is widely used as a bleaching agent in industries such as for dried foods (Schlottmann 2004), sugar (Canadian Sugar Institute 2010), textiles, and paper (De Carvalho and Schwedt 2002) and dyeing of cellulose fiber (Williams 1979)..
