Adsorption ratio define
WebJun 1, 2014 · Adsorption is a separation process where molecules tend to concentrate on the surface of the adsorbent as a result of Van der Waals force which exists between the molecules. WebMoisture sorption isotherm. At equilibrium, the relationship between water content and equilibrium relative humidity of a material can be displayed graphically by a curve, the so-called moisture sorption isotherm. For each humidity value, a sorption isotherm indicates the corresponding water content value at a given, constant temperature.

WebNov 29, 2024 · The sodium hazard of irrigation water is expressed as the ‘sodium adsorption ratio (SAR)’. Although sodium contributes directly to the total salinity and may also be toxic to sensitive crops, such as fruit trees, the main problem with a high sodium concentration is its effect on the physical properties of soil (soil structure degradation).
WebDefine Sodium Adsorption Ratio (SAR). means the index which indicates the relative abundance of sodium ions in solution as compared to the combined concentration of calcium and magnesium ions. It is calculated as follows: SAR = (Na ppm/23.0) / sq. root of [ {(Ca ppm/20.02) + (Mg ppm/12.16)} / 2] where Na=Sodium, Ca=Calcium, and Mg=Magnesium.
