概括

积极的水中船体清洁 (IWC) 可以减少排放,但可能会释放防涂料颗粒 (APP). 耐磨涂料和防腐涂料的APP释放量很低,而不是自抛光涂料,它们释放大量的APP和金属.

科学领域:

海洋涂料技术的技术
环境科学环境科学
分析化学是一种分析化学.

背景情况:

积极的水中船体清洁 (IWC) 提供了诸如减少温室气体排放和防止非土著物种运输等好处.
然而,IWC可能会释放防涂料颗粒 (APP) 和生物制剂,对海洋环境构成风险.
分析这些APP排放是具有挑战性的.

研究的目的:

适应和应用热分析方法来分析IWC期间的APP磨损.
评估不同类型的防涂层 (自抛光,防,耐磨) 的磨损行为和适用性,用于主动的IWC.
量化与不同涂层类型相关的和铜排放.

主要方法:

使用热解气色谱/质谱 (Py-GC/MS) 进行APP分析.
通过分析聚合物骨干和使用外部校准来确定APP质量.
研究了船舶船体上三种不同的防涂层类型的颗粒磨损和金属排放.

主要成果:

在模拟IWC期间,耐磨涂料和防涂料的APP释放量在模拟IWC期间是最小的 (1.2-2.1×10−4公斤和0.015公斤,分别为10,000平方米的湿面).
自抛光涂层显示出明显更高的APP磨损 (1.94.3公斤,10,000平方米的湿面).
自行抛光涂层产生的铜和排放量 (分别为2.29.5 mg/L和1.13.2 mg/L) 远远超过了水质标准.

结论:

选择防涂层对IWC期间的APP和相关金属排放产生重大影响.
自抛光涂料由于高APP和金属释放而带来了相当大的环境风险.
需要仔细考虑,以平衡IWC的好处与环境风险,特别是自抛光涂层.

Washing, Drying, and Ignition of Precipitates

Washing, Drying, and Ignition of Precipitates

After filtration, the precipitate is washed to remove coprecipitated impurities and any remaining mother liquor. Colloidal precipitates, such as silver chloride, are washed with an electrolyte (such as dilute nitric acid) to prevent the peptization of the precipitate. In the case of slightly soluble precipitates, the wash solution contains a common ion to reduce solubility. Lead sulfate, which is slightly soluble in water, is washed with dilute sulfuric acid. Similarly, wash solutions may be...
