Article Synopsis
  • A new cleaning material, Hectorite@NHCO(CH)CH, was developed to effectively detect mycotoxins in yak ghee, particularly high-fat food matrices.
  • * A modified QuEChERS-HPLC-MS/MS method was created to extract mycotoxins from sesame oil in yak ghee, utilizing Hectorite@NHCO(CH)CH to eliminate interfering substances before analysis.
  • * The method demonstrated excellent accuracy and precision, with limits of detection and quantitation ranging from 0.10 to 18.62 μg/kg and up to 62.07 μg/kg, respectively, as well as recoveries between 72.2% and 113.9%.

Rapid, sensitive and simultaneous determination of trace multi-elements in various plant food samples such as grain, oilseed, vegetable and tea is always a challenge thus far. In this work, a rapid determination method for Se, Cd, As and Pb in food samples by inductively coupled plasma mass spectrometry (ICP-MS) using slurry sampling electrothermal vaporization (SS-ETV) was developed. To improve the analytical sensitivity and precision as well as eliminate the memory effect, a gas turbulator line and signal delay device (SDD) were for the first time designed for the graphite furnace (GF) ETV coupled with ICP-MS.

A novel Ca/Mn-modified biochar recycles P from solution: mechanisms and phosphate efficiency.

Environ Sci Process Impacts

March 2022

Department of Civil and Environmental Engineering, Shantou University, No 243 Daxue Road, Shantou, Guangdong Province, 515063, China.

The excessive use of phosphate leads to severe environmental issues, such as a shortage of phosphorus resources and water eutrophication. In this study, a novel Ca-Mn-impregnated biochar (CMBC) composite was synthesized by co-pyrolysis at 600 °C for P recovery from solution. The efficiency of P-sorbed CMBC as a fertilizer was assessed pot experiments.
