Hello there
I was wondering about the correct procedure for disposing of a Pd complex catalyst (as PdCl2(dppf) or other) after it is used for a reaction in the lab. I do not feel confident about what I should do.
Thanks for helping!

Palladium is valuable and in short supply, do not dispose of it. If you can't find someone willing to buy if from you for recycle, you can send it to Standard H2, Inc., 785 N. Freedom St., Unit B, Ravenna, OH 44266
1. Washing method
The washing method is a common method for recovering trans-ditriphenylphosphine palladium dichloride II. This method requires washing the catalyst in the reaction system with an appropriate solvent to remove impurities and by-products. Then, the washed catalyst is dried to obtain the recovered catalyst.
2. Solvent extraction method
The solvent extraction method is an effective method for recovering trans-ditriphenylphosphine palladium dichloride II. This method can effectively remove impurities and by-products by extracting the catalyst in the reaction system with an appropriate solvent. Then, the extracted catalyst is dried to obtain the recovered catalyst.
3. Activated carbon adsorption method
Activated carbon adsorption method is a common method for recovering trans-ditriphenylphosphine palladium dichloride II. This method requires washing the catalyst in the reaction system with an appropriate solvent to remove impurities and by-products. Then, the washed catalyst is added to activated carbon and the catalyst is separated by adsorption. The activated carbon is dried to obtain the recovered catalyst.
Thank you for helping. I think I cannot recycle my catalyst that easily. I am using [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II). After reaction I have black dust, which might be Pd and iron itself.
Not that much yet, I am at the start of my research, few miligrams.
