Removal of tetracycline hydrochloride from wastewater by Zr/Fe-MOFs/GO composites

Abstract

Zr/Fe-MOFs and Zr/Fe-MOFs/GO composites were prepared by solvothermal methods. They were characterized by SEM, FTIR, TGA and used for efficient removal of organic contaminants from aqueous solutions.

Determination of chloropropanol with an imprinted electrochemical sensor based on multi-walled carbon nanotubes/metal–organic framework composites

“…Metal-organic framework (MOF) 18,19 is a new kind of porous material with three-dimensional network structure, which are formed by self-assembly of metal ions and organic ligands. [20][21][22] MOF feature large specic surface area and well-ordered pore structure, meriting them extensive applications in such elds as catalysis, sensors, gas isolation and storage.…”

Removal of organic contaminants from wastewater with GO/MOFs composites

“…Upon adsorption of pollutants, the Zr/Fe-MOFs/GO tends to precipitate thus effectively reducing the concentration of active sites in solution, and slowing the rate of degradation [ 34 , 35 ]. To determine the reusability of the Zr/Fe-MOFs/GO, the used Zr/Fe-MOFs/GO was washed with water, dried, and reused.…”

A Fluorescent Probe Based on Polyethyleneimine Protected Copper Nanoclusters for the Assay of Tetracycline Hydrochloride and Vitamin B12

“…[6] On the other hand, TCH is released to the environment by water discharges, excretion and urine of animal farms, which enters the ecosystem and pollutes lastly water sources. [3,7] Vitamin B12 (VB12) also called cyanocobalamin or cobalamin, is one of the essential micronutrients for humans and related to carbohydrate metabolism, nerve cell maintenance, DNA synthesis and repair, and the metabolism of enzyme. [8,9] Nevertheless, VB12 cannot be synthesized by the human body.…”

“…[10,11] For human, the daily requirement of VB12 is one to two microgramme. [7] Lacking of VB12 can result in some diseases, such as neurological abnormalities, weight loss, nausea, pernicious anemia, stroke, cognitive impairment, osteoporosis, or physical dysfunction. [11] Contrastly, excess VB12 can also easily induce some diseases, like abnormal bone marrow hyperplasia and kidney failure.…”

“…However, with the widespread application of TCH, it has brought a huge impact on the environment and human health, [4,5] such as allergic reactions, liver damage, and bacterial resistance [6] . On the other hand, TCH is released to the environment by water discharges, excretion and urine of animal farms, which enters the ecosystem and pollutes lastly water sources [3,7] . Vitamin B12 (VB12) also called cyanocobalamin or cobalamin, is one of the essential micronutrients for humans and related to carbohydrate metabolism, nerve cell maintenance, DNA synthesis and repair, and the metabolism of enzyme [8,9] .…”
