Determinaton of Sodium Carbonate and Sodium Hydrogencarbonate in Detergent Powders

Effective Capture of Carbon Dioxide Using Hydrated Sodium Carbonate Powders

The emission of CO₂ has been considered a major cause of greenhouse effects and global warming. The current CO₂ capture approaches have their own advantages and weaknesses. We found that free-flowing hydrated sodium carbonate (Na₂CO₃) powders with 30 wt % water can achieve a very high CO₂ sorption capacity of 282 mg/g within 60 min and fast CO₂ uptake (90% saturation uptake within 16 min). The ...

Sodium carbonate revisited.

We present the structure of anhydrous sodium carbonate at room temperature (phase gamma) and 110 K (phase delta) based on single-crystal X-ray diffraction data. The incommensurate phase gamma was determined almost 30 years ago in the harmonic approximation using one modulation wave and first-order satellites. In our work we use satellites up to fifth order and additional harmonic waves to model...

Germicidal Efficiency of Sodium Hydroxide, Sodium Carbonate, and Trisodium Phosphate ^

In this paper the writers present results which they obtained, for the most part, in making a comparative study of disinfectants that, might be used by poultrymen, a fact which accounts for the choice of test organisms and various other details of the technic. Although, as the title implies, this work was done chiefly with the hydroxide, carbonate, and phosphate of sodium, the paper also report...

The relationship of sodium and potassium to carbonate in bone.

Approximately a third of the total body sodium content of man, dogs, and rats is present in the inorganic portion of the skeleton (l-3). Although the magnitude of this fraction and its variability in acidosis and sodium depletion have been defined by direct analysis and by the use of isotopes, the precise position which sodium occupies in bone salt remains obscure. Harrison (4), pointing out th...
