土壤中磷酸固定作用每受外界环境之影响而有很大差异,如粘土矿物的种类,土壤反应,代换性盐基等,黏土矿物与土壤反应对于磷酸固定前,人已有较详细之报告,本文特重视代换性盐基之种类对于磷酸固定之关系。本试验以紫色土与黄壤为代表,均取于北碚。紫色土系发育于白垩纪自流井层紫色页岩,属中性而无石灰性反应,pH=7.0,黄壤系自侏罗纪灰色砂岩风化者,心土微红,pH=4.5—5.0,为避免过高之有机质,均采取心土,按照 Stoke 氏定律提取5微米(micron)直径之黏土粒,晒干后,分别以 N NaCl,N KGl,N NH_4Cl,N MgCl_2,N BaCl_2及 pH=3 HCl 处理,然后再以90%酒精洗涤至无氯为止,总之以不变更胶体之构造为原则,经处理之黏土,先分析其中之代换性盐基以及盐基代换总量,然后再测定其磷酸固定量,在酸性反应如 H~-黏土,其磷酸固定之主要因子为水化铁及水化铝,故再以 pH=2之盐酸淋洗,除去其中游离铁铝,再测定其磷酸固定量以资比较。按分析结果,黄壤胶体(<2 micron)中之(SiO_2)/(R_2O_3)为2.19,紫色土为2.56,前者盐基代换总量每百克黏土粒(<5 micron)...

Von Knorre first suggested the use of benzidine and o-tolidine for the determination of tungsten. With the latter reagent, he succeeded also in separat- ing tungstate from phosphate. Later on, o-dianisidine and vanillylidene benzidine have been proposed as precipitants for tungstate. The optimum pH ranges for the quantitative precipitation of tungstate by means of these precipitants and tetraminodiphenyl, which have not yet been found in the literature, are: benzidine pH: 2.0-5.5 o-tolidine 2.9-4.7 ...

The relation between quantitative precipitation of tungstate with benzidine and the product of concentrations of both constituents before precipitation Was studied. It is found that quantitative precipitation of tungstate ions Can be realized only when the product of concentrations of reactants before precipitation is equal to or greater than 0.8 × 10~(-5), and the moles of benzidine added must be at least equal to that of tungstate. The gravimetlic determination of tungsten by means of o-tolidine may be applied to samples containing as low as 10 mg of rungsten trioxide in 200 ml solution, if an absolute error of 0. 5 mg can be tolelxted. For larger quantities of tungsten present in sample, the absolute errors amount to only 0.1-0.2 mg. Tetraminodiphenyl may be used as a tungsten precipitant, but no advantage over benzidine Wan found in our present studies.

1.用二胺聯苯及其數種衍生物沉澱鎢酸根時,其適宜的pH範圍如下:[4,4′]二胺聯苯 pH:2.0-5.5[3,3′]二甲基[4,4′]二胺聯苯 2.9-4.7[3,3′]二甲氧基[4,4′]二胺聯苯 2.0-4.1[4]對胺聯苯氮甲烯[2]甲苯酚 1.7-3.9[3,4,3′,4′]四胺聯苯 1.7-4.8 2.用[4,4′]二胺聯苯作沉澱劑時,二胺聯苯和鎢酸根在沉澱前的濃度之乘積與後者沉澱完全與否的關係,曾加研究。 3.用[3,3′]二甲基[4,4′]二胺聯苯作沉澱劑時,能测定低至10毫克的三氧化鎢。

The extent of coprecipitation of copper with ferric hydroxide in the am- monium chloride-ammonia process has been studied. Pentavalent arsenic and antimony may be present up to 10 mg, and phosphate, 50 mg. Aluminum exerts little effect. It is found that this method yields satisfactory results. The amount of copper coprecipitated in the ferric hydroxide precipitate is negligible in practical analysis.

用氫氧化銨及氯化銨以分離銅與鐵,結果很好。氫氧化鐵中所留銅量,在實用分析上,已少至毋須考慮。用此法自多量鐵中分離少量銅份,可直接用此色法测定。五價砷與銻存在時,如不超過10毫克,或磷酸根不超過50毫克時,不影響銅與鐵的分離。鋁對分離更無影響。
