为了减少大气中的铅污染,研究了自制的巯基化壳聚糖(CTS-SH)对汽车尾气吸收液中铅的去除,讨论了时间、吸附剂用量对目标产物吸附汽车尾气吸收液中铅的影响。1实验方法1.1吸附剂质量对吸附容量的影响分别称取0.1 g,0.3 g,0.5 g,0.7 g,0.9 gCTS-SH于多孔玻板吸收瓶中,向其中分别加入去离子水15 ml,调pH为4.5,在户外温度为24℃,设定采气流量为0.8 L/min,对交通主干道
In order to reduce the lead pollution in the atmosphere, the removal of lead from automobile tail gas absorption solution by self-made thiolated chitosan (CTS-SH) was studied. The effects of time and amount of adsorbent on the absorption of lead influences. 1 Experimental methods 1.1 Adsorbent mass on the adsorption capacity were weighed 0.1 g, 0.3 g, 0.5 g, 0.7 g, 0.9 gCTS-SH in a glass plate absorption bottle, to which were added deionized water 15 ml, tune pH 4.5, outdoor temperature of 24 ℃, set the gas flow rate of 0.8 L / min, the traffic artery
