I think, most of heavy metals have it's solubility to be uptake through plants at limited pH levels approximately between 7.5- 8.5.

Dr. Gaurav Saxena : I am very curious about your question. Please can us tell where is your information about need of a high pH tolerance of plants for heavy metals phytoremediation from? Thank you.

Best regards
