4-氯苯氧乙酸钠对绿豆芽生长的影响及其残留分析

Analysis of sodium 4- chlorophenxyacetate on mung bean sprouts growth and residue

  • 摘要: 探索4-氯苯氧乙酸钠对绿豆芽生长的影响,并检测分析绿豆芽中的4-氯苯氧乙酸钠的动态残留。分别用0.5、1、2、4 mg/L四个浓度的4-氯苯氧乙酸钠溶液,通过浸泡法(方法 1)和浸泡喷洒法(方法 2)处理绿豆,发制豆芽。豆芽采收后通过测定其鲜重、轴长、轴径、根长、发芽率和产率选出较适宜的培育方法,并测定其培育的绿豆芽中4-氯苯氧乙酸钠的动态残留及市场上采集的32个样品中残留。结果提示,浸泡法中,4-氯苯氧乙酸钠浓度为1 mg/L时,产率最高(7.12)。浸泡喷洒法中,除4 mg/L组出现抑制外,其余各处理组与对照组生长情况相近,无明显促进生长作用。浸泡法中,各处理组豆芽,随着培育时间的增长残留明显降低,在最后采收时,均未检出4-氯苯氧乙酸钠。市场上32个样品中有3个样品中的4-氯苯氧乙酸钠含量在1.393.39 mg/kg之间,检出率为9.4%。适宜浓度的4-氯苯氧乙酸钠对豆芽生长有促进作用,综合考虑浸泡法更适宜豆芽的培育,在豆芽培育的过程中4-氯苯氧乙酸钠可逐渐降解,各处理组豆芽具有较高的安全性。 

     

    Abstract: The effect of different doses of sodium 4- chorophenxyacetate treatments on mung bean sprouts growth and residues were studied through the evaluation of the two cultivation methods.Mung bean sprouts were treated with four different doses of sodium 4- chorophenxyacetate nutrient solution: 0.5,1,2,4 mg / L,and grew in bean sprout machine. The fresh weight,Axis length,Axis diameter,Root length,germination rate and yield were measured after harvest.According to the results,the better cultivation method was chosen and then the dynamic residue of sodium 4- chlorophenxyacetate were determined.The residues of sodium 4- chlorophenxyacetate in thirty- two samples collected from the market were also determined.The results showed that the best yield was 7.12 for1 mg / L group in the method 1.In the method 2,except that the 4 mg / L group showed suppression,the growth of other groups were similar to the control group.In method 1,sodium 4- chlorophenxyacetate was downtrend along with time in each treatment group and no sodium 4- chlorophenxyacetate was detected in the last day.In the thirty- two samples from the market,the contents of sodium 4- chlorophenxyacetate in 3 samples were between1.39 mg / kg to 3.39 mg / kg,and the detection rate was 9.4%.The results suggested that method 1 was better than method 2 from comprehensive consideration.Sodium 4- chlorophenxyacetate could be degraded and eliminated in nurturing process of mung bean sprouts.
