Kinetics and adsorption isotherm of ammonia uptake by cation exchange resins and treatment of mixed aqueous lactate–ammonia by Mg–Al layered double oxide and the resins

• PK216LH, which is a cation-exchange resin, could remove NH 4 + in an aqueous solution. The simultaneous use of Mg–Al LDO and PK216LH not sufficiently lactate . individual two stages efficient proliferation pluripotent stem cells mass cell culture hindered by the release metabolites such as ammonia. In this work, porous strong-acid cation exchange resin (PK216LH) layered doubled oxide (LDO) were used to take up lactate, respectively. Initially, from uptake followed pseudo-second-order kinetics corresponded Langmuir adsorption isotherm, with apparent activation energy 28.2 kJ/mol maximum amount 1.38 mmol/g. contrast, enabled removal
