应用氢化物发生-原子荧光光谱法测定土壤中砷的方法研究

本文主要讨论应用氢化物发生-原子荧光光谱法,测定土壤中砷的技术。用硝酸-高氯酸分解法对样品进行预处理,探讨了共存离子对测定的影响及干扰的消除,分析了土壤标样Ess-2、Ess-3,进行了方法精密度和回收率试验。在经过优化的试验条件下,砷的检出限:0.02ug/L。回收率在91%~107%之间,相对标准偏差小于或等于7.8%。土壤标样Ess-2、Ess-3测定值与标准值相符,相对标准偏差也低于10%。表明将该法用于土壤中砷的测定操作简便、快速基体干扰少、灵敏度高、分析结果稳定可靠。     

水中总氮测定相关问题的实验探讨

通过对国家标准测定方法《碱性过硫酸钾消解紫外分光光度法》进行水样中总氮的测定,进一步理解在220nm、275nm波长处进行吸光度测定的重要性。并提出：在已经知道水样中没有氨氮、亚硝酸盐氮,只有硝酸盐氮的情况下．就能通过快速的方法一即不加氧化剂、不加压,可以进行总无机氮的测定。快速测定无机总氮对于工程应用来说很有意义。因为国标的方法需要半天时间测定。而用此方法则仅需几分钟就可完成测定。、另外对于有机物对于测定结果的影响,参考吸光度比值（A275／A220×100％）应小于20％,越小越好,超过时应予鉴别。     

Hydrochemistry of drinking water sources and water purifiers in relation to epidemiological study in Hisar,North-West India

The concern related to the drinking of reverse osmosis (RO) water containing low levels of minerals is growing day by day. This study involves the analysis of water samples from various drinking water sources in a rural site, Mirchpur village, an Indus Valley civilization site (grid location: 29° 18′ 42.3″ N, 76° 10′ 33.0″ E) of Hisar, India, along with the health survey of human subjects. The hydrochemistry of water collected from hand pumps, river canals, tube wells, submersibles, and the RO systems installed in various homes was explored for pH, EC, TH, TDS, turbidity, cations (Na⁺, Ca²⁺, Mg²⁺), anions (CO₃²⁻, HCO₃⁻, Cl⁻, SO₄²⁻, NO₃⁻, F⁻), and elements (Fe, Pb, Se) employing the ion chromatography, flame photometry, and ICP-AES techniques. Lead (Pb) and Selenium (Se) were detected in trace amounts (0.30–2.6 μg L⁻¹; 0.10–4.1 μg L⁻¹, respectively) in all the samples, including the samples collected from RO purifiers, but Iron (Fe) was not detected in RO samples even in trace amounts. The F-levels in hand pump water (HPW) and submersible water (SW) (1.9  and 1.7 mg L⁻¹, respectively) and TDS levels in SW (3048 mg L⁻¹) were found to be above WHO and BIS safe limits. TDS levels in the river canal (900 mg L⁻¹), tube well (1104 mg L⁻¹), hand pump (1170 mg L⁻¹), and submersible samples (3048 mg L⁻¹) were found significantly higher as compared to the RO personal water (ROPW; 216 mg L⁻¹) and RO supply water (ROSW; 90 mg L⁻¹). The collected epidemiological data reveals that 21%, 19%, 13%, and 12% of natives reported skin, kidney, hair fall, liver, and stomach issues, respectively, suspecting the crucial role of high TDS and fluoride levels in the area. This study also provides a comparison between the quality of RO and the direct supply water, along with correlation matrices for different parameters, which gives a rationale for the limitations of drinking direct supply water without any purification and RO water containing low mineral content.

A case study of an isolated wind powered electricity system meeting 100% of local demand

Using meteorological and electricity demand data for a 4-year period, electricity demand in Shetland was modeled to provide an estimate of the demand over a 30-year period from 1 January 1981. That modeled demand was then compared to estimated wind power output over the same period using the WAsP model. The wind farm output was estimated for a range of sizes of wind farm up to the consented 370 MW Viking Wind Farm in Shetland. Some wind power was available for 94% of the time and the 370 MW wind farm would meet 100% of demand for nearly 80% of the time. The statistics of single and accumulated deficits were calculated for a range of wind farms and estimates of the amount of additional generation capacity and additional power requirements were assessed. The study suggests that with storage, wind power in Shetland could meet all electricity demand in Shetland at around £130 to £150/MWh (excluding subsidy) and with a grid connection allowing the sale of excess power, those costs could be reduced.
