The hair can be easily contaminated by environmental fluoride. Hair fluoride from surrendings can not be washed away by common methods. With randomized blocks design we studied the washing effects of 4 kinds of detergents. Results showed that 0.25 M HC1 can be used to remove the exogenous fluoride-of the hair.The bound fluoride in the hair, however, did not decrease with the washing time and prolonged immersing.Scanning electron microscpy revealed that the hair was not morphologicaly damaged even soaked for...

The hair can be easily contaminated by environmental fluoride. Hair fluoride from surrendings can not be washed away by common methods. With randomized blocks design we studied the washing effects of 4 kinds of detergents. Results showed that 0.25 M HC1 can be used to remove the exogenous fluoride-of the hair.The bound fluoride in the hair, however, did not decrease with the washing time and prolonged immersing.Scanning electron microscpy revealed that the hair was not morphologicaly damaged even soaked for 24 hours. Hair washing with 0.25M HC1, therefore, is recommended in preparing hair samples fot analysis.

头发很容易被氟化物污染,且不易被常规洗涤方法洗脱。本研究用随机区组设计,研究了不同洗涤剂对洗脱头发表面外污染氟的洗涤效果。实验结果表明,用0.25M HCl能完全洗脱头发表面污染的氟,而且发氟值不随洗涤次数的增加和浸泡时间的延长而降低,经扫描电镜观察,0.25M HCl浸泡发样24小时,其鳞片状结构没有被破坏。推荐用0.25M HCl清洗分析发样。

Zinc powder, after rinsing with 0.5mol·dm~(-3) HCl, can reduce nitrate to nitrite quantitatively. The produced nitrite can be determined by linear sweep polarography in a solution of ferrous iron-thiocyanate without interference from nitrate. The linear range for the determination of nitrate is 5×10~(-8) to 1×10~(-6)mol·dm~(-3), and the detection limit is 4×10~(-8)mol dm~(-3) (2.48ppb NO_3~-). The effect of various factors on the reduction efficiency of zinc has been discussed. The presented procedure has been...

The produced nitrite can be determined by linear sweep polarography in a solution of ferrous iron-thiocyanate without interference from nitrate. The linear range for the determination of nitrate is 5×10~(-8) to 1×10~(-6)mol·dm~(-3), and the detection limit is 4×10~(-8)mol dm~(-3) (2.48ppb NO_3~-). The effect of various factors on the reduction efficiency of zinc has been discussed. The presented procedure has been used for simultaneously determining nitrate and nitrite in environmental water samples.

经0.5mol/L HCl清洗过的锌粉,可定量地将NO_3~-还原至NO_2~-。可间接测定5×10~(-8)mol/L~1×10~(-6)mol/LNO_3~-,检测限达4×10~(-8)mol/L(相当于2.48ppb—NO_3~-)。该法可用于环境水中痕量NO_3~-和NO_2~-的同时测定。

With cellulose as the polymer materials,monohydrate N-methylmorpholine-N-oxide(NMMO·(H_(2)O)) as the solvent,polyethylene glycol(PEG400) as the additives,asymmetric hollow fiber ultrafiltration membranes were prepared by the immersion phase inversion technique.Water was used as both the internal and external coagulant.The performances of the membrane were characterized by pure water flux.Experimental researches on treatment of oil-water emulsion by using cellulose hollow fiber membranes were performed.The results show that the treatment of oily wastewater by cellulose membrane is feasible and desirable.The oil eliminating efficiency of over 99% and oil concentration of less than 10 mg/L after the filtration were achieved, which can meet the requirement of drainage.The influences of different cleaning methods(physical cleaning,physical cleaning and 0.1 mol/L HCl solution,physical cleaning and 0.1 mol/L NaOH solution) on the cleaning of fouled cellulose membranes were investigated.The results show that the flux recovery of physical cleaning and 0.1 mol/L NaOH processes is 99%.
