铅黄

Shanghai Blue Cat cartoon products produced by roly-poly clown chrome yellow paint over the green, yellow, green, orange excessive lead paint as much as 20 times, said detection of such a high lead content are not found in the past, detection of.

上海蓝猫卡通产品的不倒翁生产的聚小丑在绿色，黄色，绿色，橙色高达20倍，过量含铅油漆铬黄颜料，说，这么高的铅含量检测不过去，检测发现。

Influence of the concentration of Cr in the leachate and quantity of Pb(CH3COO)2 of Pb(NO3)2 on the reaction of synthesizing yellow chrome was also studied. Finally, according to the criterion and standard method in GB3184-82, some yellow chrome synthesized in the experiments was sampled and the concentration of PbCrO4 in these samples was determined. The following conclusion can be drawn from these experiments.

根据中华人民共和国国家标准GB3184-82中的规定铅铬黄颜料的技术质量指标和检测方法，测定了铬黄样品中铬酸铅含量的厂迄回【、矾士牢位论父泅仰yW盯皿'S川mS达标情况，结论如下：门）反应中重铬酸盐的浓度并不需要达到前人所提出的150～2509·L'的范围，在一定条件下低于此浓度时对铬黄生成反应并无不利影响。

Characters and features: in excellent performance of coloring, in bright color of brown yellow, good tinting streng thand covering capacity, tinting strength almost equivalent to lead oxide yellow or chrome yellow, good resistance to light and atmosphere and foul gas.

性状特点：具有优良的颜料性能，色泽为鲜明的褐黄色，着色力和遮盖力都好，着色力几乎与铅黄铬黄相等，耐光、大气性、污浊气体性都非常好。

The pigment in colored cotton fibers was extracted by methanol at room temperature. The results of color reactions HCl-Mg reaction, NaBH4 reaction, NaOH reaction, FeCl3 reaction and Pb(Ac2 reaction of the pigment extractive showed that the pigment extracted by methanol was flavone or flavonol with two adjacent hydroxide groups (Table 2, Fig. 1). The results of UV spectral analysis further proved that the pigment extracted by methanol from brown fiber belonged to flavone with two adjacent hydroxide groups in B ring, and that from the green fiber contained not only flavone but also flavonols with two adjacent hydroxide groups both in A ring and B ring and indican replaced a hydroxide group at 3-site of A ring Fig.

通过盐酸－镁粉反应、四氢硼钠还原反应、碱反应、醋酸铅反应、氯化铁反应和紫外光谱吸收的分析表明，甲醇室温提取的棕色棉纤维色素可能是黄酮类化合物，B环上带有邻二酚羟基；甲醇室温提取的绿色棉纤维色素除黄酮类化合物外，还含有3-位羟基被糖甙化的黄酮醇类化合物，A、B环上都带有邻二酚羟基。

According to the description of their physical and chemical features in ancient documents, they are undoultedly two different minerals, that is, lead chromate should be As2S2 while arsenic disulfide should be PbCrO.

根据古文献中对石黄与雄黄的物理和化学特性的描述，它们无疑是两种不同的矿物，雄黄应是鸡冠石，即二硫化二砷(As2S2)，石黄应是属于铬合物的铬酸铅。

For example, white stains have MgO, hydrotalcid, alumian, containingborates calcium、 dionide, zinc oxide, arsenic, antimony oxide, silver, cerium compounds; red stains have basic lead chromate, lead kind of uranium yellow and oxymatrine of lead uranium, uranium, ND salt Cassius A50, red iron oxide and molysite CD、CU、 se reaumuria, electrolyic, MN, and so on.

例如，不黑色着色剂有氧化镁、碳酸镁、氧化铝、硼酸钙、氧化钛、氧化锌、砷酸、氧化锑、金属银、铈化合物；白色着色剂有碱式铬酸铅、铅种铀黄和氧化铀、铀酸铅、钕盐卡修斯紫金、赤氧化铁和铁盐、镉硒赤、氧化锰、锰等。

For this,experimental study was made on a new process of potential-controlled preferential flotation in a sequency of copper,lead and zinc,which used LP-01 as collector for copper mineral,DDTC as collector for lead mineral,copper sulfate and butyl...

为此，以LP-01为铜矿物的捕收剂、乙硫氮为铅矿物的捕收剂、硫酸铜和丁黄药为锌矿物的活化剂和捕收剂、石灰为矿浆电位调整剂，并在选铜、铅时配合使用铅矿物的组合抑制剂ZnSO4+YN，对该多金属复杂硫化矿进行了电位调控铜、铅、锌依次优先浮选新工艺试验研究，获得了含铜21.74%、铜回收率62.31%的铜精矿，含铅61.23%、铅回收率55.07%的铅精矿和含锌56.43%、锌回收率90.02%的锌精矿。

And then, synthesizing of middle chrome, light chrome and lemon chrome through the reaction of leachate with Pb(CH3COO)2 and Pb(NO3)2 were studied respectively.

将铬渣淋滤液与乙酸铅和硝酸铅进行反应，分别进行了中铬黄、浅铬黄和柠檬铬黄的生成试验，研究了滤液中六价铬浓度和铅盐的用量对铬黄生成反应的影响。
