In this study, black carbon from pine cone (BCPC) and acidic-modified BCPC (MBCPC) powder as a popular agricultural waste in the southeast of Iran were used for cadmium removal from aqueous solutions. The effect of various factors, such as surface chemistry and dosage of adsorbent, contact time, size of particles, initial concentration of cadmium, temperature, and pH of aqueous solutions, was investigated. The results show cadmium removal with usage of the mentioned adsorbents increased after acidic modification. It was noteworthy in this work that the removal percentage of pollutant was above 90% for suggested biosorbents. The obtained experimental data for optimum conditions were selected to model the adsorption behavior of the materials with usage of six isotherm equations via non-linear fitting method and the residual root mean square error estimation for each model. The adsorption of cadmium preferably fitted Khan and Langmuir–Freundlich isotherms for BCPC and MBCPC adsorbents, respectively. The kinetic studies via linear fitting method proved the second-order kinetic was the applicable model for the adsorption process. Thermodynamic studies show the adsorption process of cadmium onto BCPC and MBCPC was spontaneous and endothermic.

The possible combination of cowpea with moringa seed flour for the production of nutrient dense moimoi (steamed cowpea paste) and akara (deep-fat fried balls) were investigated. Composite blends of cowpea and moringa seed flour in different proportions (98:2, 96:4 and 94:6) were used in moimoi and akara production while 100% cowpea flour served as control. The proximate and sensory analyses of the products were determined using standard methods. The results showed a positive influence in the proximate compositions of these products as the proportion of moringa seed flour substitution increased. The moimoi samples ranged between 10.77 – 26.92%, 18.27 – 21.16%, 8.12 – 10.72%, 1.80 – 2.19%, 0.76 – 0.84%, 44.07 – 53.99% and 269.87 – 335.18 Kcal/100g while akara samples ranged between 9.73 – 10.77%, 19.51 – 22.12%, 7.41 – 9.90%, 2.39 – 2.71%, 0.87 – 0.93%, 54.69 – 59.00% and 320.26 – 332.08 Kcal/100g respectively for moisture contents, protein contents, crude fats, ash, crude fibers, carbohydrates and energy values. The sensory evaluation results of these products favourably competed with the control except samples D (94:6) which showed a slight difference in all parameters tested. Thus, the substitution of cowpea with moringa seed flour up to 2% and 4% proportions are adequate to produce acceptable moimoi and akara, respectively.The possible combination of cowpea with moringa seed flour for the production of nutrient dense moimoi (steamed cowpea paste) and akara (deep-fat fried balls) were investigated.
