在250—500℃的温度范围内研究了温度与过饱和度(受温度梯度控制)对热液生长黄铁矿晶体形态的影响,在平均250℃与低过饱和度时(温度梯度为0.35℃/cm,传输距离8cm以上),由螺位错生长机制生成针状晶体。随着温度和/或过饱和度的增加(平均温度达450℃和温度梯度4.6℃/cm并传输8cm以上),形成立方体—八面体—五角十二面体这样的单形序列。在淬火过程中产生极高的过饱和度时,生长机制由表面控制变为扩散控制,导致树枝状生长。黄铁矿晶习可用来圈定富含晶体成分的液体流的相对富集带。

Adsorption and Kinetic Study of Activated Carbon Produced from Post-Consumer Low-Density Polyethylene (LDPE) Wastes

引用

Advances in Chemical Engineering and Science 2021年第1期11卷 38-64页

Post-consumer polymeric wastes in form of low-density polyethylene (LDPE) can now be considered suitable as a precursor for the synthesis of low-cost activated carbon (AC). This study produced AC from LDPE using sulphuric acid (h2SO4) and potassium hydroxide (KOh) as the activating agent. The reaction conditions for pyrolysis were varied in the range of 0.50 - 2.00 M, 400°C - 500°C, and 45 - 60 minutes. Physico-chemical investigations reveal that AC yield is significantly dependent on both carbonization temperatures and time. The obtained optimum values of 446.50°C and 51.09 mins gave a yield of 24% for the base-activated carbon. The high iodine numbers obtained strongly indicate the presence of large surface area and pore volumes is further confirmed using the Scanning Electron Microscopy (SEM) analysis which reveals the presence of pores on the external surface of the carbons. Fourier Transform Infrared Technique (FTIR) analysis further shows that the synthesized compounds are purely carbon with rich oxy-gen-surface complexes on the surface which is as a result of the introduction of the chemical oxidizing agents. The produced carbons were found to have high adsorption affinity for selected inorganic ions which are: Mn7+, Co2+, and Cr6+. Adsorption isotherm results show the adsorption process to be favourable with the Langmuir isotherm parameter RL having values of hile the Freudlich adsorption model was found to perfectly fit the data at selected adsorbent dosages and adsorbate concentrations.

向数字服务提供商征收所得税的提案在OECD和许多国家来势迅猛。这些提案大体上都颠覆了一个世纪以来国际税收的实践,却没有明白无误地解释为什么要这样做。市场国长期以来都希望以来源地为依据,获得更多的税收,数字税的提案正中其下怀。但是,希望从非居民企业取得更多的税收收入,并不意味着各种拟议中的税收在设计上具有正当性、在管理上具有可操作性。本文将探讨OECD数字税提案在基本原理方面的缺陷,并建议考虑对数字化公司按收入总额征税。
