Abstract
Chemical dispersants are universally used to overcome oil spill damages. However, the toxicity related with chemical dispersants minimizes its usage as oil spill dispersants. Thus, the employment of biodegradable and environmental benign dispersants in marine environment is much needed. In this research, the capability of choline myristate [Cho][Myr] and choline oleate [Cho][Ol] were investigated to be used as oil spill dispersants. Results reported in this study illustrates that by combining these two amphiphilies, an effective dispersion is achieved. A maximum dispersion of 71 % was achieved by combining [Cho][Myr] and [Cho][Ol] with an optimal ratio of 60:40 (w/w). The dispersant to oil ratio (DOR) was 1:10 (v/v) at this optimal combination. Further, by increasing the DOR the effectiveness increases and about 78% dispersion is achieved at 1:1 (v/v). Moreover, the blend of [Cho][Myr] and [Cho][Ol] at 60:40 (w/w) ratio formed a stable emulsion than its single components.
