Journal of Textile Science and Technology 2020年第2期6卷 81-106页

This paper work involves bunch experiments to investigate the effect of contact time, pH, and adsorbent dose on the extent of adsorption by bio-composites. Adsorption capacity of Chromium (VI) onto chitosan coated with banana and areca fiber was investigated in a batch system by considering the effects of various parameters like contact time, initial concentration, pH and adsorbent dose. The chitosan and fibers (banana and areca) were then cross-linked with glutaraldehyde to remove chromium [Cr (VI)] from water via static adsorption. It was found that optimum chromium absorption capacity of chitosan was assessed at pH of 2.5 to 4.5 and contact time of 30 to 180 minutes for raw banana and areca fiber and for chitosan treated banana & areca fiber. Though optimum adsorption of chromium of chitosan was measured 34.17 ppm (85.42%) from a 100 ml solution containing 40 parts per million (ppm) of Cr (VI) at 120 minutes, pH of 3.0 and 120 milligram (mg) adsorbent dose size, use of composite will be more favorable in the point of environmental concern as well as low cost because chitosan preparation is comparatively costly then banana and areca fiber. On the other hand, untreated banana and areca fiber optimum adsorption of chromium measured 3.65 ppm (9.1%) at 180 min and, pH of 4.5 and 140 mg adsorbent dose size and 3.76 ppm (9.4%) at 180 min, pH of 4.5 and 160 mg adsorbent dose size respectively. In case of chitosan treated banana fiber, it was observed that adsorption was increased from 17.664 to 30.057 (75.14%). On the other hand, for areca fiber with chitosan, it was observed that adsorption was increased from 21.664 to 30.156 (75.39%) ppm. The Langmuir and Freundlich adsorption models were used for the mathematical description of the adsorption of chromium ion onto composites and it was found that the Langmuir adsorption isotherm was more fitted models which mean that a monolayer adsorption surface was created. After analyzing from IBM SPSS 25 software, we got the stand

Influence of Boric Acid and Sucrose on the Germination and Growth of areca Pollen

引用

American Journal of Plant Sciences 2013年第8期4卷 1669-1674页

作者： Liyun Liu Liyun Huang Yan Li Hainan Key Laboratory of Tropical Oil Crops Biology/Coconut Research Institute Chinese Academy of Tropical Agricultural Sci- ences Wenchang China.

This study investigates the effect of boric acid and sucrose on the germination and growth of areca catechu L (areca palm). Using areca pollen from Hainan, China, this study determines the influence of culture media with different concentrations of boric acid and sucrose on the germination and growth of areca pollen. Results show that the germination and growth of the pollen tube growth are highest under a boric acid concentration of 0.4 g/L to 0.6 g/L. The germination rate of areca pollen is highest in solid medium with a sucrose concentration of 40 g/L. The optimum culture medium for developing areca pollen comprises 5 g/L agar, 0.4 g/L to 0.6 g/L boric acid, 40 g/L sucrose, and water. Furthermore, areca pollen grows most rapidly approximately 1.5 h after in vitro cultivation at normal temperature, and growth stabilizes at approximately 3 h. The principle that governs the development of areca pollen is also discussed.

槟榔areca catechu L.为棕榈科木本植物,以果入药,有健胃、驱虫、行水、下气、宽中作用,是我国重要南药之一。槟榔除药用外还是南方群众喜食和馈赠之佳品,主产于海南省。由于槟榔栽培技术比较落后,虫害严重,无施肥习惯,一般产量较低且不稳定,国产槟榔远不能满足市场需要,致使每年花外汇进口槟榔以供药用。因此研究解决槟榔栽培技术、提高其产量和质量,促进槟榔生产的发展,以满足人民药用和生活需要,具有重要意义。调查研究表明,影响槟榔产量的重要因素是虫害严重。据不完全统计,每年因虫害造成的损失,一般为20％～30％,
