Control of metal ions using bis(aminoalkyl) piperazine derivatives |
| abstract |
It has now been found that certain phosphonate derivatives of bis(aminoalkyl) piperazines are good threshold agents to prevent metal ion precipitation in aqueous solutions. They also function as sequestering and/or chelating agents as do those which do not contain the phosphonate group. |
