Within the limit of experimental errors, the precision and accuracy of the method for the determination were within 3% and 4% respectively. The mean levels of EOC and BOC were in the range of 1.71 mg/kg to 5.18 mg/kg and 0.31 mg/kg to 0.68 mg/kg respectively. Analysis of organochlorine data showed the EOC content on the average was about seven times more than those of BOC. Washing of chloride from sediment fortified with an insoluble chloride, thus PbCl_2,with various concentrations of sodium nitrate (NaNO₃) solutions was investigated and washing with 0.1 M solution of NaNO₃ gave the optimum yield of chloride. Organic carbon (OC) and BOC compositions in the sediments were subjected to correlation analysis and results showed that the two correlated very well with corrected coefficient of 0.65. OC in sediments could therefore, be one of the carrier phases of BOC in sediments.</p> Samuel Afful Johannes A. M.

Nickel (II) is mostly used in industries because of its anticorrosion behaviour. Nickel (II) is present in the effluent of electroplating, plastics manufacturing, fertilizers and mining industries. It causes detrimental effect on the human health as well as environment because of its toxicity, non-biodegradability and bioaccumulation. Adsorption technique has been investigated in many researches as an effective method for not only detoxifying but also recovering precious heavy metal ions from aqueous solution. In this review various agricultural biomass based adsorbents used for removing Ni(II) from aqueous solution, optimum parameters employed and their removal efficiency from wastewater have been explored.</p> S.
