ABSTRACT:
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.
