An approximate theory was developed for anion transport involving competitive adsorption in which total monovalent anion adsorption, obeying a Langmuir‐type equation, is allocated via K v to the adsorption of Cl − and NO − 3. Employing the adsorption parameters determined from separate steady state leaching experiments, the theory successfully described the measured anion content profiles.

However, the leaching of active metals (e.g., Co, Rh) during the hydroformylation reaction seriously hinders the development of heterogeneous catalysts. Suppressing metal leaching with the use of an effective protectant is a possible solution to this problem. In this work, Co leaching was suppressed by the addition of suitable protectants (e.g., citric acid, oxalic acid, and formic acid), thus
