Book Description
Different method of preparations had been proposed by prior research studies to remove heavy metals from industrial wastewater. In this research, various PAC samples from oil palm empty fruit bunches have been prepared by physical activation using steam to study the varying operating parameters of activation temperature, activation time and steam flow rate using 2- level full factorial experimental design to screen for the best quality adsorbent. The prepared EFB samples were carbonized for 30 minutes using nitrogen gas, followed by activation with steam gas at different thermal activation temperature of 600, 750 and 900°C with steam flow rates 2.0, 3.0, 4.0 mL/min, and contact time at 15, 30 and 45 minutes respectively for the production of activated carbon. Series of batch laboratory experiments were conducted in order to investigate the feasibility of activated carbon -derived from oil palm empty fruit bunches for the removal cadmium from aqueous solution through the adsorption process. Assessment was carried out by studying the influence of removal of Cadmium due to pH, adsorbent dosage and agitation rate to select the optimum production conditions for the novel PACs. Based on the analysis of variance (ANOVA) and batch adsorption test, the results indicated that activated carbon derived from 900°C, steam flow rate- 2ml/min and activation time of 15 minutes had maximum adsorption capacity at 2 mins (0.273 mg/g) for the removal of cadmium (97.2 %), R2 = 0.999 in the aqueous solutions with a yield of 21.8% and correlation coefficient R2 = 0.992. The optimum PAC sample selected was investigated through adsorption tests on aqueous solution of cadmium using the adsorption isotherms such as Langmuir and Freundlich to evaluate or predict the adsorption characteristics. In the isotherm studies, the trend of Langmuir and Freundlich coefficients ( , , and n) were in agreement with cadmium initial concentration trend. Batch adsorption studies showed that equilibrium time of 2 mins of agitation at 150 rpm was needed for the adsorption of cadmium on the activated carbon during experiment. The regression coefficient (R2) showed that Langmuir isotherm (R2= 0.984) fits the result better than Freundlich isotherms (R2 = 0.950). The characterization of PACs produced was measured to evaluate its quality and the results showed that 900°C activation temperature, 15 minutes activation time and 2.0 ml/mins steam flow rate had a high surface area of 635.16m2/g. These characteristics were observed to have favoured 900°C activated temperature, 15 mins activation time and 2.0 ml/mins steam flow rate with respect to adsorption of cadmium. EFB based- PAC would be promising in such a way that the industrial oil palm solid residue would.

Book Description
Author Biography: Dr. Mohammad Abdul Mannan was born at a simple family of a small village, Aktarpur, Rangiarpota, Jibonnagar, Chuadanga, Bangladesh. He has obtained B.Sc. (Civil Engineering) degree with first class, MSc in Civil Engineering and PhD in Concrete technology. He has started carrier as lecturer at BIT Rajshahi (now RUET), Bangladesh followed by AJP consulting firm, then Universiti Malaysia Sabah (UMS) and is now a Professor of Department of Civil Engineering, Universiti Malaysia Sarawak, Malaysia. He is the inventor of few construction products. Based on 30 years of experience in teaching, professional practice and research, his vision is to be excellence in research on Innovative Construction Material and Structure. Book Description: Due to a high demand in construction and furniture industries worldwide, natural resources such as stones and wood as non-renewable resources are being depleted. Thus, researchers are focusing on renewable resources as alternative materials. As such, the utilisation of abundant solid wastes and byproducts, which are discharged from agriculture, industry and municipalities present an alternative to the conventional materials for the construction and furniture industries. These solid wastes and byproducts, when properly processed have shown to be effective and can readily meet design specifications. Agricultural solid wastes from oil palm distributors such as Oil Palm Shell (OPS) and Empty Fruit Bunch (EFB), which are abundant in agro-based countries, present an interesting alternative to the conventional aggregate in lightweight concrete and artificial plank production, respectively. At present, palm oil producing countries are Barkina Faso, Benin, Burundi, Cameroon, Central African Republic, Colombia, Costa Rica, C�te d'Ivoire, Democratic Republic of Congo, Ecuador, Equatorial Guinea, Gabon, Gambia, Ghana, Guinea Bissau, Guinea, Honduras, India, Indonesia, Liberia, Malaysia, Mexico, Nigeria, Papua New Guinea, Peru, Republic of Congo, Senegal, Sierra Leone, Tanzania, Thailand, Togo, Uganda, Venezuela and others. In Malaysia, oil palm plantations cover over 5 million hectares, and annual production of OPS as solid waste from 450 oil palm mills is more than 6 million tons. This large amount of OPS as a renewable green aggregate can contribute to overcoming the over dependence on depletable resources for concrete production. The civil engineering projects are of a larger scale; they need sustainable materials in order to gain a greater momentum of growth. The major technical characteristics of OPS solid waste must be primarily understood before each particular use. Therefore, there is a need to highlight the importance of OPS to be used in the construction industry.
