Bottle material

Portions of a 20 g sample of the oxidant salt, prepared exactly as the published description [1], had been used uneventfully dining a few days. Subsequently, as a 2 g portion was tipped out onto glazed paper, it ignited and burned violently, leading also to ignition of the bottled material [2],...

As a consequence of this state of the art, the need and justification for establishing a conventional method for reproducible inertness testing of refill-bottle materials was identified in our laboratory a few years ago. In our opinion, a practical, cost-efficient and relatively quick standard test procedure which could also be used by surveillance labs was worth development. Within an European project (Castle 1997, Jetten et al. 1999), an investigation was undertaken to elucidate the feasibility of such a quick test method for refillable PET bottles, with respect to evaluating their inertness concerning the uptake and subsequent release of chemicals and sensory-active compounds. Before starting method development, the following considerations were made and... 

The success of this reduction depends upon the quality of the sodium hydrosulfite. The reagent should be taken from a fresh bottle material which has stood in the laboratory for a long time jjrobably has undergone oxidation. 

The preliminary characterization analysis on the bulk material from river Ruhr revealed also the necessity of a fortification step. However, for these materials, it was decided to opt for a low concentration level (down to around 0.1 pgL-1 per compound) achieved by fortifying the bottled materials just before dispatch of the samples (two days maximum in advance). Due to the chosen spiking procedure, a check of the integrity of the sample received by the laboratories was considered necessary and achieved by a control of the weight of the bottle. Additionally, and once again because of the spiking procedure used, for these materials participants were requested to analyse samples immediately after receipt. 

Generally, this clause refers to an international standard, if such exists. If necessary, specific preconditions and methods of sampling or pre-treatment steps for the preservation of the samples (e.g., filtration, acidification, bottle material, storage conditions) are given. 

The choice of bottle material and bottle size to suit the intended purpose of the analysis is important. The concentration of any disinfectants such as chlorine, chlorine dioxide or ozone must be measured immediately after sampling. 

In Canada, Haycore recycles tubs, lids, injection-molded plastics, and other non-HDPE and PET bottle materials from curbside collection program. The company produces high-quality clean flake.Markets for the material include pallets made by Granville Composite Products, protective plastic spacers for shipping made by PBI Industries, and recycling containers made by Buckhom Canada. ...
