After adsorption, the acute toxicity of TNT red water reduced greatly, compared with that of unprocessed TNT red water. The removal efficiencies of 2,4-dinitrotoluene-3-sulfonate (2,4-DNT-3-SO3-) and 2,4-dinitrotoluene-5-sulfonate (2,4-DNT-5-SO3-) were 80.5% and 84.3%, respectively. The Regional Meteorological Centre, Chennai has issued a red alert warning for Cuddalore, Mayiladuthurai, Thanjavur, Tiruvarur, Nagapattinam and Karaikal on Friday. At the conditions of initial pH = 6.28, 20 degrees C and 3 hr of agitation, under 160 g/L AC, 64.8% of COD was removed. The sorption isotherm was in good agreement with Redlich-Peterson isotherm. The adsorption process was an exothermic and physical process. This novelty shaped pillow is made from durable polyester material and is sure to add some character and depth to your room. The results showed that the sorption kinetics of COD removal from TNT red water onto AC fitted well with the pseudo second-order model. This Minecraft TNT Cube Red Cushion (14x14) is a great addition to your bedroom or living room. This study focused on sorption kinetics and equilibrium sorption isotherms of AC for the removal of COD from TNT red water, and the changes of water quality before and after adsorption were evaluated using high performance liquid chromatography, UV-Vis spectra and gas chromatography/mass spectroscopy.

Since the composition of TNT red water was very complicated, chemical oxygen demand (COD) was used as the index for evaluating treatment efficiency. We treated 2,4,6-trinitrotoluene (TNT) red water from the Chinese explosive industry with activated coke (AC) from lignite.
