济南市水文地质特征对地下水污染的影响分析

从环境水文地质学的角度出发，对济南市地下水污染的主要途径和方式，以及局部地下水重污染区进行了较为详细的分析，济南市地下水污染以浅层地下水污染为主，局部地区深层地下水也已受到污染，并有进一步加重的趋势，地下水严重超采，造成多处地表塌陷和降落漏斗，并成为济南市地下水的重污染区。     

试论我国陆地再生能源资源及其特征

在世界矿物能源资源日趋减少的今天,再生能源资源引起人们广泛的兴趣,特别是陆地再生能源资源更是如此。本文对我国陆地再生能源资源——太阳能、风能、水能、生物质能——中的前两种能源资源进行了分区及分省计算,并依据全国已有的调查及普查资料,对后两种源能资源进行了分省及分区统计,在此基础上又对全国陆地再生能源资源的数量、分布及特征进行了对比分析,并从宏观上提出了开发利用我国陆地再生能源资源的建议和设想。     

Preconcentration and determination of trace copper(II) in natural water using silica gel modified with 1-(2-pyridylazo)-2-naphthol

Trace copper (II) in water can be preconcentrated using silica gel modified with 1-(2-pyridylazo)-2-naphthol (PAN) and be determined spectrophotometri-cally. The conditions for the preconcentration were studied. The method was applied to both artificial and natural water samples and the results suggest that copper (II) of ppb level in water can be measured accurately after the preconcentration.

In situ preparation of g-C3N4/Bi4O5I2 complex and its elevated photoactivity in Methyl Orange degradation under visible light

A graphite carbon nitride(g-C_3N_4) modified Bi_4O_5I_2 composite was successfully prepared insitu via the thermal treatment of a g-C_3N_4/Bi OI precursor at 400°C for 3 hr.The as-prepared g-C_3N_4/Bi_4O_5I_2 showed high photocatalytic performance in Methyl Orange(MO) degradation under visible light.The best sample presented a degradation rate of 0.164 min~(-1),which is 3.2 and 82 times as high as that of Bi_4O_5I_2 and g-C_3N_4,respectively.The g-C_3N_4/Bi_4O_5I_2 was characterized by X-ray powder diffractometer(XRD),scanning electron microscopy(SEM),transmission electron microscopy(TEM),Raman,X-ray photoelectron spectroscopy(XPS),ultraviolet-visible diffuse reflectance spectra(DRS),electrochemical impedance spectroscopy(EIS) and transient photocurrent response in order to explain the enhanced photoactivity.Results indicated that the decoration with a small amount of g-C_3N_4 influenced the specific surface area only slightly.Nevertheless,the capability for absorbing visible light was improved measurably,which was beneficial to the MO degradation.On top of that,a strong interaction between g-C_3N_4 and Bi_4O_5I_2 was detected.This interplay promoted the formation of a favorable heterojunction structure and thereby enhanced the charge separation.Thus,the g-C_3N_4/Bi_4O_5I_2 composite presented greater charge separation efficiency and much better photocatalytic performance than Bi_4O_5I_2.Additionally,g-C_3N_4/Bi_4O_5I_2 also presented high stability.·O_2~-and holes were verified to be the main reactive species.
