In this work, activated carbon obtained from agro- based material, mustard seeds were used as an adsorbent for the adsorption study of crystal violet (CV) and citric acid (CA). The characterization of synthesised carbon material was performed by various techniques, such as FTIR, SEM, TGA and XRD. FTIR absorption bands of activated carbon exhibited the presence of functional groups on the surface of activated carbon and SEM images showed the impregnation of the pores on the surface of the synthesised activated carbon. Adsorption experiments were conducted to study its capacity as an adsorbent, under various conditions such as concentration, agitation time and temperature. The data acquired from concentration variation found to fit well with Freundlich isotherm. It was shown that the adsorption of dye and acid were better described by the second order kinetic model. Positive values of ΔHo indicated that the process is endothermic and negative values of ΔGo confirmed feasibility of the system. The results showed that microwave activated carbon was more effective for the removal of crystal violet.

SummaryThis community-based cross-sectional study was carried out in the tribal population of randomly selected villages of Jabalpur district, Madhya Pradesh, central India. A total of 200 married men and women aged 15–49 years were interviewed to explore their knowledge, experience and health-seeking behaviour related to sexually transmitted infections (STIs). Though 91% of respondents were aware of STIs, the sexual route was mentioned by only 19% as the route of transmission. Around 18% reported a need for social isolation from persons with STIs. Though 88% of the respondents felt modern medicine was the best remedy for STIs, only a few of them used medical treatment while suffering from an STI. Twenty-seven per cent of respondents resorted to traditional healers, and 30% utilized home remedies for STI treatment. The study highlights a need for generating STI awareness amongst the tribal population of the region through a needs-based behaviour change communication (BCC) strategy.
