Boundary flux modelling for purification optimization of differently-pretreated agro-industrial wastewater with nanofiltration

The design and operation of membrane purification plants implies the prediction and control of dynamic fouling phenomena as a key to succeed. In this research article, the boundary flux theory was used to set-up and control the operating framework and model the performance of a NF membrane operation, for the purification of olive mill wastewater (OMW) previously conducted to different pretreatments. Olive oil is produced by means of a technological process which avoids the use any chemicals.

Enzyme-mediated extraction of limonene, linalool and linalyl acetate from bergamot peel oil by pervaporation

Bergamot peel oil is highly attractive for food and pharmaceutical industries due to its content of valuable essential oil, which is enriched with high-added valuable compounds, such as limonene, linalool and linalyl acetate. Nevertheless, there are some limitations for the separation of such compounds. In this framework, pervaporation (PV) technology was proposed as a tool for the separation of limonene, linalool, and linalyl acetate from bergamot oil by using two different commercial organophilic membranes (PDMS-1070 and POMSPEI).

Enantioselective ultra high performance liquid and supercritical fluid chromatography: the race to the shortest chromatogram

The ever-increasing need for enantiomerically pure chiral compounds has greatly expanded the number of enantioselective separation methods available for the precise and accurate measurements of the enantiomeric purity. The introduction of chiral stationary phases for liquid chromatography in the last decades has revolutionized the routine methods to determine enantiomeric purity of chiral drugs, agrochemicals, fragrances, and in general of organic and organometallic compounds.
