Speciation of As(III)/As(V) in water samples by a magnetic solid phase extraction based on Fe3O4/Mg–Al layered double hydroxide nano-hybrid followed by chemiluminescence detection

Cauliflower‐like NiCo2O4−Zn/Al Layered Double Hydroxide Nanocomposite as an Efficient Electrochemical Sensing Platform for Selective Pyridoxine Detection

“…The NiCo 2 O 4 −Zn/Al LDH nanocomposite was prepared via a simple route according to the procedure described elsewhere . Firstly, 4 mL of the LDH and NiCo 2 O 4 suspensions containing 0.1 g of synthesized materials were individually ultrasonicated for 1 h. Afterward, the two suspensions were directly mixed and subjected to sonication for 2 h at ambient temperature to obtain the NiCo 2 O 4 −Zn/Al LDH nanocomposite.…”

Advances in Sample Extraction

“…Layered double hydroxides (LDHs) are relatively recent promising sorbents for enriching anions owing to their excellent anion-exchange capacity, high porosity, and high specific surface area, as has been shown in many reports in the past few years . They have been particularly used in SPE to extract various analytes, such as As­(III)/As­(V), chromate, PAHs, phthalate esters, metal ions, phenols, etc.…”

Utilizing of Ag@AgCl@graphene oxide@Fe3O4 nanocomposite as a magnetic plasmonic nanophotocatalyst in light-initiated H2O2 generation and chemiluminescence detection of nitrite

“…Beef sausage, chicken sausage and Salami sausage were chosen for the analysis and Two minutes later, the CL reaction was triggered by manual injection of 0.5 mL of the mixed solution of 1.2 mol L −1 Na 2 CO 3 and 37.5 µmol L −1 uranine according to our previous reported method [30]. Finally, the CL intensity was recorded in a time course measurement mode and used as an analytical signal.…”
