This chapter emphasized number of recent techniques for the analysis of acrylamide in food. Despite presence of several analytical methods for acrylamide determination, these techniques still require further development. After review of this chapter, one can conclude that UPLC/MS/MS represents a powerful technique with high-resolution separation of acrylamide, short run time, and high specificity that excludes the matrix interferences of the extract.
Numerous studies have been performed on the conversion of individual types of waste into activated carbon (AC). However, this study focused on the evaluation of the simultaneous conversion of different types of wastes (palm, paper, and plastic wastes) into AC via copyrolysis. The tartrazine adsorption capacity onto the produced AC was optimized. The results showed that the carbon content of the AC improved as the calcium hydroxide concentration varied from 0.0 to 2.0 mol L−1.
Wastes must be managed properly to avoid negative impacts that may result. Open burning
of waste causes air pollution which is particularly hazardous. Flies, mosquitoes and rats are
major problems in poorly managed surroundings. Uncollected wastes often cause unsanitary conditions
and hinder the efforts to keep streets and open spaces in a clean and attractive condition.
During final disposal methane is generated, it is much more effective than carbon dioxide as a
The widespread use of pesticides leads to considerable attention for pesticide detection and removal.
Therefore, in the first part of this work, a simple and facile solid phase extraction (SPE) procedure for
separation of malathion from soil and water samples, has been established. Malathion was recovered at a
pH of 2.0–3.0 with limit of detection (LOD) of 0.026 ng L1. While in the second part, the kinetics of the
batch adsorption removal of malathion from aqueous solutions was investigated. Results showed that
Ultra performance liquid chromatography coupled to mass spectrometry was used for the simultaneous
separation and determination of reducing monosaccharides (fructose and glucose), a non-reducing disaccharide
(sucrose) and oligosaccharides (kestose and nystose) in HILIC mode. The chromatographic separation
of all saccharides was performed on a BEH amide column using an acetonitrile–water gradient
elution. The detection was carried out using selected ion recording (SIR) acquisition mode. The validation
