The article conveys some information:
Heavy metal ion removal from wastewater has gained intense attention due to metal toxicity, bioaccumulation tendency, and persistence. Adsorption is a most promise method because of its simplicity and efficiency. This work reports preparation of an EDTA-functionalized covalent organic framework (COF) for heavy metal ion removal. A COF, TpPa-NO2, was reduced to TpPa-NH2 using a Na2S2O4 reductant, then EDTA dianhydride was grafted on the TpPa-NH2 to form TpPa-NH2@EDTA via post-modification. COF morphol. and structure remained unchanged after post-modification. TpPa-NH2@EDTA displayed excellent heavy metal ion adsorption performance (e.g., soft Lewis acids [Ag+, Pd2+], hard Lewis acids [Fe3+, Cr3+], borderline Lewis acids [Cu2+, Ni2+]) with removal efficiencies all >85% within 5 min due to the EDTA strong chelation effect. TpPa-NH2@EDTA also showed high adsorption ability in a pH ≥3 environment with an adsorption capacity >50 mg/g for six representative heavy metal ions. This work provided an idea to use COF materials to remove heavy metal ions from wastewater. In addition to this study using 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde, there are many other studies that have used 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4Recommanded Product: 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde) was used in this study.
2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde(cas: 34374-88-4) is a member of phloroglucinol derivatives. Phloroglucinol derivatives are a major class of secondary metabolites. Phloroglucinol compounds can be classified into monomeric, dimeric, trimeric and higher phloroglucinols, and phlorotannins.Recommanded Product: 2,4,6-Trihydroxybenzene-1,3,5-tricarbaldehyde
