标准范围
ISO 15181-6:20 12规定了根据ISO 15181-1中给出的程序测定从防污涂料释放到人工海水中的曲洛吡利的量的方法。Tralopyril在水中不稳定,水解降解形成3-溴-5-(4-氯苯基)-4-氰基-1H-吡咯-2-甲酸(BCCPCA)。ISO 15181-6:20 12规定了通过热处理和定量人工海水提取物中BCCPCA降解产物浓度来加速释放的曲洛吡利转化为该降解产物的方法,并给出了在规定的实验室条件下曲洛吡利释放速率的最终计算。ISO 15181-6:20 12旨在允许通过分析单独的亚组分,同时测定给定防污涂料(例如锌)可释放的曲洛吡利和其他杀生物剂。根据ISO 15181-1生成的人工海水提取物样品。当与ISO 15181-1联合使用时,通过该方法定量释放速率的实际限度为0.36 μ g cm?2D?1到270微克厘米?2D?1.低于该范围的释放速率的定量需要使用人工海水中曲洛吡利定量限小于2 μ g/l的分析方法。
ISO 15181-6:2012 specifies a method for determining the amount of tralopyril that has been released from an antifouling paint into artificial seawater in accordance with the procedure given in ISO 15181-1.Tralopyril is unstable in water and degrades hydrolytically to form 3-bromo-5-(4-chlorophenyl)-4-cyano-1H-pyrrole-2-carboxylic acid (BCCPCA). ISO 15181-6:2012 specifies a method for accelerating the conversion of the released tralopyril into this degradation product by heat treatment and quantifying the concentration of the BCCPCA degradation product in the artificial seawater extract, and gives the final calculation for the release rate of tralopyril under the specified laboratory conditions.ISO 15181-6:2012 is designed to allow the concurrent determination of tralopyril and other biocides that can be released by a given antifouling paint (for example, zineb) through the analysis of separate sub-samples of an artificial seawater extract generated in accordance with ISO 15181-1.When used in conjunction with ISO 15181-1, the practical limits for quantifying release rates by this method are from 0,36 μg cm?2 d?1 to 270 μg cm?2 d?1. The quantitation of release rates lower than this range requires the use of an analytical method with a limit of quantitation for tralopyril in artificial seawater of less than 2 μg/l.
