Low density polyethylene (LDPE) and high (HDPE) are the principal plastics present in solid plastic waste found out as main components of microplastics marine terrestrial environments. Currently, efforts have been made to develop new effective methods ensure identification separation waste, ensuring necessary purity obtain quality economically competitive recycled products. In this contribution...

Rice is a staple food in Vietnam, and the concern about rice much greater than that for other foods. Preventing fraud against this product has become increasingly important order to protect producers consumers from possible economic losses. The adulteration of done by mixing, or even replacing, high-quality with cheaper rice. This highlights need analytical methodologies suitable its authentica...

This work focuses on the use of chemometric techniques for identifying activated sludge process abnormalities. Chemometric methods combined with image analysis can improve activated sludge systems monitoring and minimize the need of analytical measurements. For that purpose data was collected from aggregated and filamentous biomass, biomass composition on Gram-positive/Gram-negative bacteria an...

Identification of clay minerals based on chemometric analysis of measured infrared (IR) spectra was suggested. IR spectra were collected using the diffuse reflection technique. Discriminant analysis and principal component analysis were used as chemometric methods. Four statistical models were created for separation and identification of clay minerals. More than 50 samples of various clay miner...

This work represents a comprehensive analysis of pedada fruit (Sonneratia caseolaris) as less desirable fruit, but valuable content such pectin which obtained through extraction using microwave assisted (MEA) method. Pectin is water-soluble fiber widely used functional component in the food and pharmaceutical industry. The focuses on comparison profile from Kepok banana peel. In addition, effec...

This paper presents the application of metabolomic techniques to determine the presence of microbial influenced corrosion (MIC). In a previous study, the extracellular metabolites expressed from pipe biofilm was identified by analysing the passing water. This investigation extends this work by successfully applying a chemometric statistical analysis to the extracellular metabolomic profile of a...

In light of the frequent occurrence counterfeit food sold in global commercial markets, it is necessary to verify authenticity tasty natural-plant-based products by checking their labels, as well pricing and quality control. Lemon juice has repeatedly been victim fraud attempts manufacturers lower price products. Electronic noses are used many fields, including beverage industry, for classifica...
