Determination of As, Sb, Se, Te and Bi in milk by slurry sampling hydride generation atomic fluorescence spectrometry
2003
A simple and fast analytical procedure has been developed for the determination of As, Sb, Se, Te and Bi in milk samples by hydride generation atomic fluorescence spectrometry (HG-AFS). Samples were treated with aqua regia for 10min in an ultrasound water bath and pre-reduced with KBr for total Se and Te determination or with KI and ascorbic acid for total As and Sb, the determination of Bi being possible in all with or without pre-reduction. Slurries of samples, in the presence of antifoam A, were treated with NaBH(4) in HCl medium to obtain the corresponding hydrides, and AFS measurements were processed in front of external calibrations prepared and measured in the same way as samples.

Selective recovery of gold from electronic waste using 3D-printed scavenger
2017
Around 10% of the worldwide annual production of gold is used for manufacturing of electronic devices. According to the European Commission, waste electric and electronic equipment is the fastest growing waste stream in the European Union. This has generated the need for an effective method to recover gold from electronic waste. Here, we report a simple, effective, and highly selective nylon-12-based three-dimensional (3D)-printed scavenger objects for gold recovery directly from an aqua regia extract of a printed circuit board waste. Using the easy to handle and reusable 3D-printed meshes or columns, gold can be selectively captured both in a batch and continuous flow processes by dipping …

El precio de ser itinerante. Viajes, acompañamiento y espacios cortesanos de la reina Leonor de Sicilia (r. 1349-1375)
2021
This article is an attempt to detail which logistical, economic and human implications had the itinerancy of the medieval monarchy. For this reason, the paper focuses on the characteristics of the itinerancy of Eleanor of Sicily, third wife of Pedro the Ceremonious and queen of the Crown of Aragon between 1349 and 1375. Through the analysis of her documentation, from chancery and treasury resources, it has been possible to establish an itinerary of the queen for three years, from 1354 to 1357. The analysis of this itinerary allows us to see the confluence of the royal couple entourages and the consequences of the beginning of the Dos Pedros war. At the same time, the paper focuses on the pe…

Cold vapour atomic fluorescence determination of mercury in milk by slurry sampling using multicommutation
2004
Abstract A highly sensitive mechanized method has been developed for the determination of mercury in milk by atomic fluorescence spectrometry (AFS). Samples were sonicated for 10 min in an ultrasound water bath in the presence of 8% (v/v) aqua regia, 2% (v/v) antifoam A and 1% (m/v) hydroxilamine hydrochloride, and after that, they were treated with 8 mmol l −1 KBr and 1.6 mmol l −1 KBrO 3 in an hydrochloric medium. Atomic fluorescence measurements were made by multicommutation, which provides a fast alternative in quality control analysis, due to the easy treatment of a large number of samples (approximately 70 h −1 ), and is an environmentally friendly procedure, which involves a waste ge…
