提出了联苯胺－Ｈ２Ｏ２－辣根过氧化物酶（ＨＲＰ）伏安酶联免疫分析体系测定植物病毒烟草花叶病毒（ＴＭＶ）和烟草环斑病毒（ＴＲＳＶ）的新方法。ＨＲＰ标记的羊抗兔酶标记抗体ＩｇＧ－ＨＲＰ可以催化Ｈ２Ｏ２氧化联苯胺的反应,其氧化产物在Ｂｒｉｔｏｎ－Ｒｏｂｉｎｓｏｎ（ＢＲ）缓冲溶液中在－０．６２Ｖ（ＳＣＥ）左右产生灵敏的线性扫描二阶导数伏安峰,可以测定ＩｇＧ－ＨＲＰ。根据ＩｇＧ－ＨＲＰ与植物病毒及其抗血清的免疫反应,可以间接测定植物病毒。本法测定ＴＭＶ的检出限为０．２５ｎｇ／ｍＬ,线性范围为０．２５～５０００ｎｇ／ｍＬ;测定ＴＲＳＶ的检出限为１．５ｎｇ／ｍＬ,线性范围为１．５～３０００ｎｇ／ｍＬ;测定ＴＭＶ烟草病叶澄清液的最高稀释比为１∶１００００。检测灵敏度高于酶联免疫吸附显色光度法（ＥＬＩＳＡ）

THE PREPARATION OF CROSSLINKED N，O—CARBOXYMETHYL CHITOSAN RESINS AND THEIR ADSORPTION PROPERTIES FOR TRIGLYCERIDE IN SERUM

Crosslinked N,O-carboxymethyl chitosan resins which can selectively adsorb triglyceride,were prepared by the reaction of N,O-carboxymethyl chitosan with glutaraldehyde solution.Adsorption experiments were performed by adding the resins to the serum.The results showed that this type of adsoirbent could cut down the concentration of triglyceride in serum by 56.4%(3.35mg/g resin)at most,while concentration of the total protein(TP) decreased only by 10.9% at least,so this novel adsorbent can be used to cure hypertriglyceridemia by hemoperfusion in the future.

Bio-adsorption of dyes from aqueous solution by powdered excess sludge (PES): Kinetic,isotherm, and thermodynamic study

Over 30 million tons of excess sludge is discharged from rural municipal sewage plants annually in China and it is predicted that this figure will keep increasing. However, most of the excess sludge is dumped in landfills except for minor applications. In this study, based on low-cost and recycling waste, the excess sludge was used to adsorb organic dyes from aqueous solution after being directly dewatered. The powdered excess sludge (PES) presents selective adsorption property to cationic dyes. Statics batch adsorption experiments of malachite green (MG) on PES were performed to evaluate the effects of pH, adsorbent dosage, and initial MG concentration. Results revealed that the bio-adsorption equilibrium of MG on the PES can be quickly achieved at 30 min with maximum percentage adsorption of 84% at pH 7, initial dye concentration of 20 mg L^?1, and adsorbent dosage of 1.5 g L^?1. Moreover, the adsorption kinetics follows a pseudo-second-order pathway, and the equilibrium adsorption data could be described well by the Langmuir isotherm equation. Intra-particle diffusion is not the only rate-controlling step in the entire adsorption process. The adsorption process is endothermic, spontaneous, and random. PES can be used as a low-cost adsorbent for refractory cationic organic dye in effluent.
