Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. 29823-18-5, Name is Ethyl 7-bromoheptanoate, molecular formula is C9H17BrO2, belongs to bromides-buliding-blocks compound. In a document, author is Megalopoulos, Fivos A., introduce the new discover, SDS of cas: 29823-18-5.
Bromate removal from water by acid activated and surfactant enriched Red Mud – the case of cooling water
Red Mud is a hazardous by-product of the Bayer process, used to produce alumina from bauxite, with ability to adsorb anions from water. Acid activation and enrichment with CetylTrimethylAmmonium Chloride (CTAC), a cationic surfactant, are employed to enable it to remove bromate initially from spiked double-distilled water. CTAC enrichment is found to substantially improve Red Mud’s bromate removal ability in comparison to acid activation alone. Fourier Transformation Infrared Spectroscopy is used to evaluate the effectiveness of the enrichment process. Maximum CTAC loading is 0.037 g per g acid activated Red Mud (AARM). Adsorption is faster after CTAC enrichment. pH increase is found to adversely affect both AARM and acid activated CTAC enriched Red Mud’s (CTAC-AARM) bromate removal capability, yet CTAC-AARM’s ability proves more resistant to pH changes. Adsorption data fit best the Langmuir isotherm model for both adsorbers. The R-2 values for AARM and CTAC-AARM are 0.955 and 0.964 respectively. Maximum adsorbable bromate quantity is almost 2.5 times higher for CTAC-AARM in comparison to AARM. Finally, both Red Mud adsorbers are compared with respect to their ability to remove bromate from cooling water; an industrial matrix rich in competing ions. As cycles of concentration and pH appreciate, bromate adsorption is hindered regardless of the adsorber used. However, CTAC-AARM still performs better in removing bromate. It is proven that after suitable processing, Red Mud can re-enter the industrial cycle by playing a role in bromate removal from industrial waters.
