Contents 2 Chemical-biological Waste

A lot of ready-to-use scintillation cocktails are available. Besides counting efficiency, chemical, biologic, and environmental hazards should be reflected when choosing a cocktail. Since vials and their contents are radioactive waste, number and volume of vials should be as small as possible. [Pg.190]

The wastewater from syntheses of chloro- -trlazlne herbicides Is a clear, colourless mixture of wastes from the chemical reaction and from washing the product. It has a total organic carbon content of about 1200 mg a total Kjeldahl nitrogen concentration of about 810 mg of N a biological oxygen demand after 5 days of about 530 mg of O2 L, and contains NaCl at about 35 g L the pH Is about 12 (14). [Pg.174]

Dave et al. (1985) reported the biodegradation of toxic cyanide waste. The effluent was pretreated with hot alkah digestion and chemical coagulation followed by biological aeration. The HCN content in black gram and other seeds at a level of 1 mg/100 g flour was completely destroyed in 20-minute cooking (Dwivedi and Singh 1987). [Pg.322]
