Aniline is extremely recalcitrant to degradation ,under, methanogenic ,conditions, (De et al. 1994). However, biodegradation of some compounds has been observed to occur after acclimatization of sludge in ,wastewater, treatment test systems (O’Connor and Young 1989; Ekici et al. 2001) and in sediments ,under, anaerobic ,conditions,.

The highest efficiency often can be obtained when the operating pH is adjusted to between 4 and 4.5 at 20 mg/L of aluminum ions concentration (Allen 1980). Thus, aluminum sulfate is suitable for removing DCS present in mechanical pulp that is used for the production of newspaper ,under acidic conditions,.

Panetal. recovered 79% of the lignin using ,conditions, of 170°C, 1.1% w/w H 2 SO 4, 65% v/v ethanol for 60 minutes. Lignin recovery. The recoverey of lignin from ethylene glycol organosolv pulping can be effected by 3 times dilution with acidified water. The lignin ,precipitates, and forms spherical aggregates ranging from 0.5-2.5µm.

Chlor-Alkali Process. The Chlor-Alkali Process is an industrial process where an aqueous solution of sodium chloride (also called brine) is decomposed electrolytically by Direct Current, producing chlorine, hydrogen, and sodium hydroxide solution.The overall reaction of the process is: 2 NaCl + 2 H 2 O→Cl 2 + H 2 + 2 NaOH. takes place in two parts, at the anode and at the cathode.

A dense molybdenum oxide layer was fabricated on nickel foam (MoO 2 @Ni) and used as the cathode in the 1-ethly-3-methylimidazolium chloride/AlCl 3 ionic liquid electrolyte aluminum ion battery. Study on the electrochemical performance demonstrated that the cathode could not only exhibit a discharge potential of 1.9 V which is higher than most of the studied metal oxide cathodes of Al ion ...

Etherification of cellulosic surfaces can be achieved ,under, highly alkaline ,conditions, by treatment with suitable organic epoxides or chlorides (Belgacem and Gandini 2005; Habibi 2014). One of the most important applications of such reactions, from the standpoint of paper manufacture, is in the preparation of cationic starch products, which are often used as dry-strength additives (Roberts 1991).

Hydrated lime or quicklime is mixed with water, to give an alkaline slurry, which, neutralises the low pH of acids,. Milk of lime can also be used to avoid the need for slurrying equipment. Often insoluble calcium salt is precipitated during the reaction which can help to remove impurities from the system.
