Studies on Systems of Lithium and Potassium Halides from Salt Lake and Bittern Resources（V）──The Quaternary Reciprocal System Li￣＋■Br￣－，I￣－－H＿2O and Boundary Ternary System NH＿4Br－NH＿4I－H＿2O at 25℃

摘　　要：he solubilities , refractive indexes of saturated solutions of the quaternary re-ciprocal system Li￣+ , Br￣(-) ,I￣(-)H_(2)O and its boundary ternary system NH_(4)Br-NH_(4)I-H_(2)O at 25℃ have been investigated using isothermal method. In the titleternary system which belongs to Roozeboom Ⅳ type, there are two limited solid so-lutions. Entering into the quaternary system, the region of the solid solutions re-duces and disappears with the increase of Li￣+ , and finally, the quaternary systembecomes a simple system.he solubilities , refractive indexes of saturated solutions of the quaternary re-ciprocal system Li￣+ , Br￣(-) ,I￣(-)H_(2)O and its boundary ternary system NH_(4)Br-NH_(4)I-H_(2)O at 25℃ have been investigated using isothermal method.
