摘要： Anticorrosion and pH-stabilized brine solutions useful for air dehumidification processes are disclosed. Inorganic and organic buffering agents or mixtures thereof can be added to halide solutions of alkali metals, alkaline earth metals, or mixtures thereof, to stabilize the pH and/or minimize corrosion of the dehumidifier system. The solution, with or without additional corrosion inhibitors, can offer improved protection as compared to conventionally used inhibitors during repeated dehumidification cycles. In addition, new corrosion inhibitors are disclosed, such as heteropoly anions and phosphonates, which offer improved corrosion protection in closed or open systems during repeated dehumidification cycles or selected applications. These corrosion inhibitors offer improved protection for metals when used with the buffers disclosed herein. The buffered halide solutions, such as lithium chloride, calcium chloride and mixtures thereof, mixed with one or more commonly used corrosion inhibitors also offer improved corrosion protection for metals in closed or open systems.
