T
he prospect of producing bioethanol from biomass available locally is in the interest of widespread sustainable growth and
development. The novelty of our study focused on maximizing the recovery and purity of bioethanol from dates by subjecting
the process to specialized treatment for removal of water and toxic species. Bioethanol production from dates of the Fard and
Khalas cultivars is relatively unexplored, and was achieved by adopting standard protocol of thermal sugar extraction followed by
fermentation and distillation. Water de-contamination of the product utilizing molecular sieve treatment led to enhanced purity of
bioethanol (98%). Co-treatment with sodium borohydride resulted in reduced levels of toxic species Cr
3+
, Cr
6+
and As
3+
by about
20%. The speciation study was conducted using hybrid liquid chromatography/mass spectrometry (HPLC-ICP-MS). A built-in
dynamic reaction cell facilitated detection of the species of interest. Elemental profiling of bioethanol samples employing standard
ICP-MS demonstrated that the levels of trace elements were higher in general for the Fard dates. Our research is significant from the
perspective of deploying surplus dates for biofuel production to obviate competition for arable land. The study could make a useful
contribution to ongoing research associated with climate change.
