PIN LAYOUTFor a description of pin functions, refer to the μPD71055 Data Sheet (document number: IC-1921).Note This pin is connected to GND or V DD in the chip. To enhance the power supply to handle noise, this pin can be connected to the power supply pin of the board to improve the noise resistance performance.4Data Sheet A18501EJ3V0DS2. ELECTRICAL SPECIFICATIONSThis section describes only the differences with the μPD71055.For electrical specifications other than those below, refer to the μPD71055 Data Sheet (document number: IC-1921).Absolute Maximum RatingsParameter Symbol Conditions Ratings Unit Power supply voltage V DD−0.5 to +6.0 V Input voltage V I−0.5 to +6.0 V Output voltage V O−0.5 to +6.0 V Caution Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any parameter. In other words, the absolute maximum ratings are values at which the product maybegin to suffer degradation. Therefore the product must be used under conditions that ensure thatthe absolute maximum ratings are not exceeded.Recommended Operating RangeThis is the same as the μPD71055.

211018618_原子吸收光谱法测定土壤和沉积物中的铅
第52卷第3期 辽 宁 化 工 Vol.52，No. 3 2023年3月 Liaoning Chemical Industry March，2023收稿日期： 2022-04-22作者简介： 萧婉仪（1992-），女，广东省广州市人，助理工程师，研究方向：场地调查。
原子吸收光谱法测定土壤和沉积物中的铅萧婉仪（广东省地质实验测试中心，广东 广州 510000）摘 要： 对土壤和沉积物中的铅的采用混合酸分解、稀硝酸提取、火焰原子吸收分光光度计及石墨炉原子吸收光谱仪分析测定，火焰原子吸收分光光度计可测到10-9 g ·mL -1数量级，石墨炉原子吸收法可测到10-13 g ·mL -1数量级。
该方法准确度和精密度较高，样品处理过程简单、快捷，分析检测的结果满足HJ 491—2019、GB/T 17141—1997技术规范要求。
关 键 词：原子吸收光谱法；土壤；沉积物；铅中图分类号：TQ134.3+3 文献标识码： A 文章编号： 1004-0935（2023）03-0453-04土壤污染主要分为无机污染和有机污染物。
其中土壤有机污染重金属比较突出，主要是重金属不能被微生物有效分解。
土壤重金属污染物主要有汞、镉、铅、铜、铬、砷、镍、铁、锰、锌等。
其中铅是人体唯一不需要的微量元素，是一种稳定且很难降解的污染物。
其长期在环境中累积，造成慢性铅中毒的主要原因就是环境污染。
据测定，当人体内血铅质量浓度0.30 μg·mL -1时，就会引发中毒症状。
据统计，长期接触微量元素铅的人，铅阻碍血细胞的形成，影响血液进入脑组织，损害小脑及大脑皮层，干扰代谢活动，使营养物质与氧气供应不足，引起脑小毛细管内皮层细胞肿胀。
因此，高效准确检测土壤中铅的含量是很有必要的。
本文采用混合酸溶液分解土壤样品中的铅，硝酸提取，用原子吸收光谱法测定。
该方法处理过程简单，高效准确。

BERYLLIUM COPPER ALLOY 172 (UNS C17200) per
ASTM B 194
Properties of BERYLLIUM COPPER:
Chemical composition: Cu 98.1%, Be 1.9%
Temper as stamped: TD01
Properties after heat treatment (TH01):
Hardness: 36-43 Rockwell C
Mechanical Life: 100 Cycles Min.
Density: .298 lbs/in3
Electrical Conductivity: 22% IACS*
Resistance: 10 miliohms Max
Operating Temperature: -55°C/+125°C
Melting point: 980°C/865°C (liquidus/solidus)
Stress Relaxation†: 96% of stress remains after 1,000 hours @ 100 ºC ; 70% of stress remains after 1,000 hours @ 200 ºC
*International Annealed Copper Standard, i.e. as a % of pure copper.
†Since BeCu loses its spring properties over time at high temperatures; it is rated for continuous use up to 150°C. For applications up to 300°C, Mill-Max offers many contacts in Beryllium Nickel. Contact Tech Support for more info.
