Humidity Solutions

A saturated solution of sodium chloride can be used as a constant-humidity solution at 25°C, a relative humidity of 75% is produced. A specification for sodium chloride is contained in the Food Chemicals Codex (FCC).

A more ecological interpretation of multiple equilibria is given by Brovkin et al. (1998). They develop a conceptual model of vegetation-precipitation interaction in the western Sahara which is applied to interpret the results of comprehensive models. The conceptual model finds three solutions for present-day and LGM climate one of these, however, is unstable to infinitesimally small perturbations. The humid solution is shown to be less probable than the arid solution, and this explains the existence of the Sahara desert as it is today. For mid-Holocene climate, only one solution is obtained. Application of the conceptual model to biospheric feedbacks at high latitudes (Levis et al, 1999) yields only one solution for the present-day conditions.

The key parameters to control the photocatalytic activity include the type of contaminant, airflow rate and residence time, relative humidity, solution pH, initial concentration, reactor parameters, and t)q)e of substrate. But the photocatalytic efficiency is the result of the complete set of structural and textural properties of the semiconductor coating, for example, crystal size, porosity, pore size distribution, and total mass deposited (thickness), but mainly depends on the total surface effectively irradiated with UV photons.
