1.Results showed that the effect of car- boxymethyl larch tannin on removing COD from ATT dye effluents is better than that of tannin but inferior to PAM under a- cidic condition(pH value from 1 to 3)with the concentration of carboxymethyl larch tannin less than 50 mg/L.
结果表明,羧甲基落叶松单宁在酸性条件下(pH值为1～3),投放量小于50 mg/L时,对ATT染料废水的COD去除效果好于单宁,较聚丙烯酰胺差；
2.At first, the adsorption behaviors of Cd(II) on collagen fiber immobilized black wattle tannin, larch tannin and bayberry tannin were investigated.
首先研究了胶原纤维固化黑荆树单宁、固化落叶松单宁和固化杨梅单宁对Cd(II)的吸附特性。
3.The chemical components and the physical and chemical properties of the extracts of every layer are researched primarily in this article.The results indicated that sterol and terpene,naphtha and grease,lactone and coumarone,organic acid,cardiac glycoside,tannin and athraquinones.Tannin and athraquinones are reported for the first time in Ganoderma lipsiense(Batsch) G.F.Atk.
对树舌灵芝各溶剂提取物进行化学成分及理化性质的初步研究,结果表明:树舌灵芝中有甾醇和三萜、挥发油和油脂、内酯、香豆素、有机酸、强心甙、鞣质、含氧杂环及蒽醌类等成分,其中鞣质、含氧杂环及蒽醌类成分以前未见报道。
4.ZM-A’s best proportion is that Tannin : amine :aldehyde =1:4:3.5, the reaction pH =6.5, Tannin : soft water =1:1, the best reaction temperature is 80℃, reaction time is 4h.
ZM-A和ZM-B絮凝剂制备过程中,过量的游离甲醛、水分、反应温度和pH值对产品的絮凝性能和稳定性都有一定的影响。
5.Thus, it can be considered that larch tannin is derived from catechin and its tanning properties should be basically identical with those of catechol tannins and areca tannin.
因此,可认为落叶松单宁中的一部分是以真儿茶素为母体的一种单宁,其鞣革性能基本上应与儿茶单宁及槟榔单宁相同。
6.Object To study the tannin components in the leaf of Corylus heterophylla Fisch ex Bess Methods The tannin components were extracted with solvents and separated on Toyopearl HW 40 (F) and Sephadex LH 20 columns They were identified by 1HNMR, 13 CNMR, FABMS, CD and 2 dimensional 1H 1 HCOSY spectra and chemical methods Results 8 compounds were obtained for the first time from the plant They were quercetin 3 O β D glucuronide (Ⅰ);
目的 黑龙江省富含鞣质成分的榛子叶的开发与应用。 方法 利用 1 HNMR、1 3CNMR、FABMS、CD谱及1 H- 1 HCOSY二维谱与化学方法鉴定从榛子叶中分离得到的化合物的结构。
7.Ozone treatnent stimulated the PPO activity,speeding up the oxidization of VC and tannin and consuming of Titratable acid and rostering the brown of fresh tissue. CT2 fumigation treatment reduced the loss of VC and tannin,refrained the PPO activiey and degraded the frowning rate of the fresh tissue. But some berry was sufferde from SO2 and had SO2 remained in the frcsh tissue.
而CT2号保鲜剂处理可减少果肉可滴定酸、抗坏血酸和单宁物质的损失,降低果肉组织的酶促褐变率,但部分果实受到SO2漂白伤害且果肉组织有SO2残留。
8.The result was confirmed that tannin in skin of walnut kernel had effect of separating oxygen and anti-oxidizing during storage. The content of tannin and acid value showed remarkable negative correlations.
试验结果表明:在贮藏过程中,核桃仁种皮中的单宁首先起到隔氧抗氧化的作用,与核桃油脂的酸价呈显著的负相关;
9.More than 90% tannin exist in rapeseed shell, which takes about 12%~19% of the whole seed and is the main factor for its black appearance. Tannin is one of the antinutrional factor.
油菜籽的种皮约占全籽的12％～19％，全籽中90％以上的单宁都存在于种皮之中，单宁是使菜籽种皮呈黑色的重要因素之一，也是菜籽饼粕作为饲料的主要抗营养因子之一。
10.The adsorption capacities of Cr(VI), Pb(II), Cd(II), Hg(II), Pt(II), Pd(II), V(V), Bi(III) and Mo(VI) on the immobilized bayberry tannin were determined.
树皮、改性活性炭及生物质对Pb(II)和Cd(II)的吸附容量分别为46-110mg/g和46-58mg/g。 合成树脂对Pt(II)和Pd(II)的吸附容量为55.6mg/g和20-100mg/g。
