摘要

研究发现，在超声波冲击下，黑碳对乳胶系统中乳化剂的吸附活性增强，这有助于乳胶的脱稳和弹性组合物的释放，而无需使用凝固剂。研究表明，由于黑碳吸附了不可生物降解的白炭黑、树脂皂形式的乳化物质和脂肪酸，废水的总体污染程度降低，COD 的处理效率高达 98%。研究表明，在 SKS-30ARK 橡胶的胶乳阶段用 P245 级高结构黑碳进行液相填充（重量比-橡胶：黑碳=100:100），可将不可生物降解的白醇含量降至 0.1 mg/dm3，并将废水的生物毒性指数提高至 83%。

Ecological and Technological Aspects of Liquid-phase Filling of Styrene-butadiene Rubber with Black Carbon in an Ultrasonic Field

It has been found that black carbon exhibits increased sorption activity in relation to the emulsifying agents of the latex system under ultrasonic impact, which contributes to destabilization of the latex and the release of the elastomeric composition without the use of coagulating agents. It was revealed that as a result of the black carbon sorption of non-biodegradable leukanol, emulsifying substances in the form of resin soaps and fatty acids, the overall pollution of wastewater is reduced, and treatment efficiency of up to 98% is achieved in terms of COD. It has been shown that the liquid-phase filling of SKS-30ARK rubber at the latex stage with high-structural black carbon of grade P245 at a ratio, wt. part — rubber: black carbon = 100 : 100 allows to reduce the content of non-biodegradable leukanol down to 0.1 mg/dm3 and increase the biooxidability index of wastewater to 83%.

期刊介绍： The Journal "Ekologia i promyshlennost Rossii" («Ecology and Industry of Russia») is aimed to promote acquaintance of the world scientific and technical public and specialists, interested in the problems of the environment protection, with advanced achievements of the science and engineering practice on securing of stable (self-supporting) evolution within the limits of the United Nations accepted recommendations (RIO 92 and RIO+20). A circle of papers includes basic researches and engineering decisions, analytical and methodical operations, reviews on journal subjects. The journal lays special emphasis on methodical elaborations, analytical investigations in the sphere of creating the ecological culture of the population, to the features of ecological education in higher schools of the country for the sake of actualization in specialists'' consciousness of the scientific necessity to know environmental problems of the modern civilization and paths of their settlement. Original papers and investigations of scientists and specialists on separate themes occupy an independent niche of issues under the «Cover story» heading. The journal task is to promote practical implementation of scientific and engineering decisions in the field of decrease of anthropogenic load on the biosphere and environment protection (open lectures, round tables, discussions and so forth). Ecology and Industry of Russia is an informational reference book about the newest developments of the Russian and foreign scientists and the companies realized in Russia, the CIS and Baltic countries, and far-abroad countries. The journal publishes information reports about holding in Russia and abroad the international, all-Russian and regional congresses, conferences, and symposiums related to the journal subjects.
