分析从原始和酸性的离子释放到去离子水清洗(AW) Fluoroaluminosilicate眼镜用电感耦合Plasma-Optical发射光谱学(ICP-OES)

文摘

目标和目的:评估离子的释放到去离子水中硅酸fluoroalumino眼镜(LG26Sr)之前和之后的酸洗液和决定的影响酸洗眼镜。材料与方法:标本fluoroalumino硅酸盐眼镜(实验眼镜;LG26Sr生和酸清洗)储存在聚乙烯(PE)管在37°C在去离子水为28天的时间。玻璃免费解决方案收集后1、3、7、14、21、28天。离子的累积释放从眼镜24小时28天计算比较模式离子释放的去离子水。释放的离子进行分析通过使用电感耦合Plasma-Optical发射光谱学(ICP-OES)。ICPOES能够同时进行多元素分析确定离子水溶液的浓度。结果与讨论:(a)的离子释放fluoroalumino硅酸盐眼镜(实验眼镜;LG26Sr生和酸清洗)观察到的历史时刻。看到,离子的释放减少会随着时间的推移,有少量的离子在本周四公布。 (b) Acid washed glasses increased the amount of release of fluoride (F) and aluminium (Al) ions while the releases of strontium (Sr) ions were decreased. (c) The acid washing of the glasses demonstrated the higher amounts of release of F ions compared to Al ions. Although the amount of Al is increased after acid wash but it was too low as compared to F ions. (d) Immediately after week 3 the release of Al ions from raw glasses were decreased. Conclusion: (a) Considerable amounts of ions were released from both the glasses (raw and acid washed) into deionized water throughout the experimental period. (b) The release of ions was decreased after reaching a peak value and minimal quantities were released in week four. (b) F and Al ions were released more from AW glasses as compared to raw glasses. (c) Release of Al ions were suddenly dropped in week 4. (d) Release of Sr ions were greater from raw than AW.
