Abstract: PURPOSE:To efficiently separate and recover indium in high selectivity using simple operation by bringing a specific hydrophobic compound having N- nitrosohydroxyamino group into contact with a solution containing indium. CONSTITUTION:A hydrophobic compound (e.g. N-nitrosophenylhydroxylamine ammonium salt), expressed by the formula (R1 is 3-30C straight-chain, branched or alicyclic alkyl or alkenyl; R2 is phenylene, naphthylene, hydrophenylene or hydronaphthylene; X is H, inorganic or organic ammonium ion or alkali metal; n is 0, 1 or 2) and having N-nitrosohydroxyamino group is prepared. The resultant hydrophobic compound is then brought into contact with a solution containing indium to selectively absorb the indium thereon. The indium is subsequently eluted with a strong acid to selectively separate and recover the indium.

Abstract: PROBLEM TO BE SOLVED: To obtain the subject membrane slight in thickness unevenness and good in surface smoothness, and to provide a method for producing such a membrane. SOLUTION: This membrane is obtained by the following process: polyoxyethylene is added to an agar- and/or agarose-contg. compound followed by addition of water as necessary, the resultant mixture is made into a sheet- like gel, which is then dried at 0-40 deg.C under a load of 0.01-2 kgf/cm2; alternatively, this membrane can be obtained more efficiently by the following process: one side or both sides of the above sheet-like gel is (are) laminated with porous material and/or water-absorbing material followed by drying the gel at 0-40 deg.C under a load and then removing the porous material and/or water-absorbing material.

Abstract: PROBLEM TO BE SOLVED: To provide a membrane containing agar and/or agarose and having a small dispersion of a membrane thickness is and a good surface smoothness, and its manufacturing method. SOLUTION: A mixture formed by adding hydroxyalkylcellulose to a compound containing agar and/or agarose and water as occasion demands is made into a sheet-like gel. Thereafterm while a load of 0.01-2 kgf/cm2 is applied to the sheet-like gel, the sheet-like gel is dried at 0-40 deg.C to obtain a membrane containing the agar and/or the agarose. A porous material and/or water absorbing material are laminated on one side or both sides of the sheet-like gel comprising the mixture which contains the compound containing the agar and/or the agarose and the hydroxyalkylcellulose. The sheet-like gel and the material are dried at 0-40 deg.C while a load is being applied. Then, thereby the membrane containing the agar and/or the agarose can be more effectively manufactured.
