With the need of airplane for long endurance flight, the pilot raises new demand for the gas-water content of the product generated by OBOGS. For this reason, this paper conducted experiments with the system on the two types of oxygen-rich molecular sieves — NaX type and LiX type, which are used currently for domestic OBOGS under different operating conditions, conducted sampling analysis of the bleed...
A low-cost adsorbent modified kaolin clay (MKC) was synthesized and utilized for Cr(VI) removal from aqueous solution. Adsorption experiments were carried out as a function of adsorbent dosage, solution pH, Cr(VI) mass concentration, contact time, electrolyte, and temperature. It is found that the adsorption efficiency is high within a wide pH range of 2.5–11.5, and equilibrium is achieved within...
