A low-cost and facile route to the synthesis of bimetallic glycolato zirconate (Na2Zr(C2H4O2)3) and homometallic glycolato cerate (Ce(C2H4O2)), which can be used as alkoxide precursors for sodium zirconium oxide (and/or zirconia by sol–gel process) and ceria materials, has been developed from the reaction of inexpensive starting materials via the oxide one-pot synthesis (OOPS) process. Both com...

A system for the regeneratlon of caustic soda solutlons used In etching aluminum Invokes the hydrolysis of sodium aluminate to llberate free sodium hydroxide and produce a dry, crystalllne hydrated alumlna byproduct. The system has been used extenslvely In Japan, and, by adjusting process parameters, can be adapted to North American practice. By otlllting the system in a typical plant, soild ai...

As a means of decontaminating instruments possibly exposed to Creutzfeldt-Jakob disease, the World Health Organization has recommended immersion and autoclaving in sodium hydroxide. However, this recommendation has raised concerns of possible damage to autoclaves, and hazards to operators as a result of the caustic vapors. A series of experiments has been conducted that demonstrate that there a...

We have established a simple method for assaying the quantity of soluble bromine in the discharge tubes of an extra-high-pressure mercury discharge lamp. Each discharge tube is destroyed in 5 ml of 10 mM sodium hydroxide, and the recovered sodium hydroxide solution is analyzed by suppressed-ion chromatography using gradient elution. We have clarified that this method can assay less than 1 micro...

Although the literature contains a number of reports regarding the bactericidal efficiency of certain specified concentrations of sodium hydroxide against various test organisms, very little of this information is presented in a manner suitable for mathematical analysis. To obtain the data required for analysis, an experimental study was made of the bactericidal efficiency of sodium hydroxide. ...

Organic compounds containing thiourea function find many industrial, agricultural, pharmaceutical and analytical applications. Consequently, convenient, reliable, rugged and cost-effective methods for ensuring the quality of commercial products based on it are highly desirable. The case with which hydrogen peroxide in the presence of an excess of sodium hydroxide oxdatively desulphurise the thi...

This study is focused on investigating the influence of the parameters for dechlorination of polychlorinated biphenyls (PCB) using electron beam. The dechlorination process was studied using concentrated solutions of polychlorinated biphenyls. 2-propanol with/without water, ethanol, 1,2,3,4-tetrahydronaphthalin and tetrahydrofurane were used as solvents. The results of the research showed that ...
