The invention has compositions of matter and process aspects. The compositions of matter aspects relate to a class of new organic compounds, viz., intermediates which are sulfur and nitrogen containing hydrocarbons covalently bonded to trialkoxysilane and those intermediates covalently bonded to a solid inorganic support such as silica. The process aspect comprises two processes, viz., (1) a process for making the new class of compounds, and (2) the process of removing and/or concentrating certain ions such as noble metal ions and other transition metal ions, from solutions thereof admixed with other ions which may be present in much higher concentrations by forming a complex of the desired ion(s) with a compound as stated, e.g., by flowing the solution through a column packed with the compound, breaking the complex, e.g., by flowing a receiving liquid through the column to remove the desired ion(s) in solution in the receiving liquid and recovering the desired ion(s) from the receiving liquid.

The invention has compositions of matter and process aspects. The compositions of matter aspect relate to two classes of new organic compounds, viz., A. intermediates which are sulfur-containing hydrocarbons covalently bonded to trialkoxysilane and B. that class of intermediates covalently bonded to silica, e.g., sand and silica gel. The process aspect comprises two processes, viz., (1) A process for making the two new classes of compounds A and B, and (2) the process of removing and concentrating certain ions, such as noble metal ions and other transition metal ions, from solutions thereof admixed with other ions which may be present in much higher concentrations by forming a complex of the desired ion(s) with a compound of class B, e.g., by flowing the solution through a chromatography column packed with the compound, breaking the complex, e.g., by flowing a receiving liquid through the column in much smaller amount than the amount of solution passed through it to remove and concentrate the desired ion(s) in solution in the receiving liquid and recovering the desired ion(s) from the receiving liquid.
