Usually Al in a MAX phase is removed by HF acid or similar ways, is there any suitable solvent to remove indium? Thank you.

Dear Dr. Queiroz,
Thank you for answering this question. I am sorry that I didn't make the question clear enough. I don't mean to remove Indium residues, but remove Indium which is one component element of MAX phase. For instance, etching indium from Ti3InC2 (a MAX phase) to obtain Ti3C2. Thank you.
Al is easily etched to obtain MXenes, i did not work with indium before, but you can start firstly by modifying the synthesis parameters (working with small particle sizes and increasing temperature and synthesis duration)
